Production companies

I have done some research into production companies to determine which one would produce our film. Callum and I spent a lot of time trying to figure out of our film is British Independent, or mainstream. 

Film production/distribution companies in red are companies that might not produce our film. 
Film production/distribution companies in green are companies that might produce our film.

 Mainstream

Dreamworks
DreamWorks, is a California film studio which develops, produces, and distributes films, video games and television programming. It has produced or distributed more than ten films with box-office grosses totaling more than $100 million each. Today, most of DreamWorks' films are marketed and distributed by The Walt Disney Studios

This would not produce our film because according to the IMDB it does not have any existing British films.

20th Century Fox
20th Century Fox Pictures, is one of the six major American film studios as of 2011. Located in the Century City area of Los Angeles, just west of Beverly Hills, the studio is currently a subsidiary of Rupert Murdoch's News Corporation.

This would not produce our film although it is possible that their subsidary company Fox Searchlight would.

Disney

Disney, is an American diversified multinational mass media corporation headquartered in Walt Disney Studios, Burbank, California. It is the largest media conglomerate in the world in terms of revenue.

This would not produce our film because the Disney target audience is way too low for our film.

Fox Searchlight

Fox Searchlight Pictures, is an American film division of the Fox Entertainment Group alongside the larger Fox studio 20th Century Fox. It specializes in independent and British films, alongside drama and horror as well as non-English-language films, and is variously involved with the production and/or distribution of these films.

It is possible that Fox Searchlight might produce and/or distribute Happily Ever After

Metro-Goldwyn Mayor

Metro-Goldwyn-Mayer Studios Inc., is an American media company, involved primarily in the production and distribution of films and television programs. Once the largest and most glamorous of film studios. MGM went bankrupt and heads of their subsidary companies took over.

It is unlikely that MGM would produce our film as it is not famed for their rom-coms, neither have they released anything recently.

New Line Cinema

New Line Cinema, is an American film studio. It was founded in 1967 by Robert Shaye and Michael Lynne as a film distributor, later becoming an independent film studio. It became a subsidiary of Time Warner in 1996 and was merged with larger sister studio Warner Bros. in 2008

It it not a film studio which would produce a film like Happily Ever After.

Paramount Pictures

Paramount Pictures Corporation is a film and television production/distribution studio, consistently ranked as one of the largest (top-grossing) movie studios. It is a unit of American media conglomerate Viacom.

It is not a film studio which would be likely to produce Happily Ever After

Universal

Universal Studios Inc. (also known as Universal Pictures), is an American motion picture studio, owned by Comcast through its wholly owned subsidiary NBCUniversal, and is one of the six major movie studios. It is one of the longest-lived motion picture studios to be located outside of Hollywood.

It is possible that Universal would produce our film but it is more likely that they would produce it through the subsidiary Working Title

Warner Bros

One of the major film studios, it is a subsidiary of Time Warner, with its headquarters in Burbank, California and New York. Warner Bros. has several subsidiary companies, including Warner Bros. Studios, Warner Bros. Pictures, Warner Bros. Interactive Entertainment, Warner Bros. Television, Warner Bros. Animation, Warner Home Video, New Line Cinema, TheWB.com, and DC Entertainment

It is possible Warner Bros would produce our film solely because generally their target audience is the same as ours. Also the range of different types of film produced by Warner Bros is wide.

Working Title

Working Title Films is a British film production company, based in London owned by Universal Studios. The company was founded by Tim Bevan and Sarah Radclyffe in 1983. It produces feature films and several television productions.

Judging by the films it has previously produced (According to IMDB), the target audience that Working Title genrally make films for, and the fact that it is a British Subsidiary of a major Mainstream American production company, working title is probably the most likely company to produce Happily Ever After.

 Independent

I have not researched a large amount of independent companies, partly because their aren't many but also because my film is a mainstream Rom-Com blockbuster.

Artificial Eye
Artificial Eye is a British film distributor, specialising in foreign-language and art house films for cinema and home entertainment.

It would not produce our film.

BBC Films

BBC Films is the feature film-making arm of the BBC. It has produced or co-produced some of the most successful British films of recent years, including An Education, StreetDance 3D, Fish Tank, Stage Beauty, A Cock and Bull Story, Nativity! and Match Point.

I would not produce a mainstream romantic comedy like Happily ever After

Channel 4 
Film4 Productions is a British film production company owned by Channel Four Television Corporation. The company has been responsible for backing a large number of films made in the United Kingdom.

Because it produced The Inbetweeners Movie, it is possible that it would produce Happily Ever After

Studio Canal
StudioCanal  is a French-based production (as StudioCanal S.A.) and distribution (as StudioCanal Images S.A.) company that owns the third-largest film library in the world.

It is possible that it would play a part in the production of our film if we were to work with Working Title as the two companies have worked together on comedy films in the past.

Conclusion

After researching into existing Rom-Coms and their production & distribution companies, I have determined that our film would be produced by a British subsidiary of a mainstream American company like Notting Hill which was produced by Working Title - a British subsidiary of Universal Pictures.
