International Co-production

Shows or dramas that are produced by two TV companies, each in different countries. Especially in the most recent decades, an animated TV show has always been produced by at least two studios in some way, since animation is expensive and labor-intensive.

Anime

 * The Mysterious Cities of Gold—France (DiC)/Japan (N.H.K., Studio Pierrot)
 * Ulysses 31—a collaboration between DiC and TMS.
 * Spider Riders—Made with Bee Train, TV Tokyo and Yomiko Advertising in Japan and Cookie Jar Entertainment in Canada.
 * Halo Legends—USA/Japan co-op like Gotham Knight
 * The anime of Samurai Gun was co-financed by ADV Films.
 * Like Torchwood, the first Bakugan Battle Brawlers series was a fully Japanese production (TMS Entertainment and Japan Vistec along with Sega TOYS Co.), but follow-up series New Vestroia and Gundalian Invaders were made in conjunction with North American licensors Nelvana Enterprises and Spin Master (both Canadian), due to the fact that the original series was far more popular in Canada and the US than it was in Japan and the local numbers weren't good enough to warrant a follow-up.
 * The Valérian and Laureline animated series—France/Japan
 * Oban Star-Racers—France/Japan
 * Ghost in the Shell (1995 film) -- Made by Production I.G. (Japan) and produced by Manga Entertainment (UK/USA)
 * Dead Leaves—Made by Production I.G. (Japan) and Studio Gainax (Japan), and produced by Manga Entertainment (UK/USA)
 * Afro Samurai—Written and animated by Studio Gonzo (Japan); cast, produced and distributed by Funimation Entertainment (USA)
 * Rurouni Kenshin Seisohen, a.k.a. Samurai X: Reflections—Made by Studio DEEN (Japan); produced by ADV Films (USA)
 * All Yu-Gi-Oh! films and series after the first two have been funded/produced by 4KidsEntertainment
 * GX was a co-production between the Japanese companies and Dong Woo Animation.
 * The Animatrix—Features nine segments across which animation, writing and directing duties are handled by American, Korean, and (mostly) Japanese talent.
 * Ghost in the Shell: Stand Alone Complex - Made by Production I.G. (Japan) and produced by Manga Entertainment (UK/USA) and Bandai Entertainment USA.
 * Tekkon Kinkreet: Animated by Studio 4°C (Japan), directed by an American living in Japan, and scored by British rock band Plaid.

Films -- Animation

 * The animated film adaptations of The Hobbit and The Return of the King—USA/Japan; directed and character-designed by Rankin/Bass Productions, animated by Topcraft (the studio that made Nausicaa of the Valley of the Wind)
 * Batman Gotham Knight (2008) -- Co-produced by DC Comics and four Japanese animation studios.
 * Film/Interstella555 was animated in Japan (Through Toei Animation), with a soundtrack by French band Daft Punk.
 * The First three Bionicle films were a collaboration between Creative Capers Animation in America, LEGO in Denmark, and CGCG & Wang Film Productions in Taiwan.

Films -- Live-Action

 * Mongol—A collaboration between Russia, Mongolia, Kazakhstan, and Germany, with a significant amount of filming done in China.
 * Paris Je Taime—Features segments by filmmakers from around the world, including France, Mexico, the USA, England, and Japan.
 * The Three Musketeers 2011—A co-production between the UK, Germany and France, with talent from all three countries (along with American Logan Lerman in the lead).
 * Similar with Inglourious Basterds, shot in the same studio (Babelsberg), which was a German/American co-production.
 * The Harry Potter films—USA (Warner Bros and, for a time, 1492 Pictures)/UK (Heyday Films). 1492 Pictures is Chris Columbus's own production company, which left the series when he did. Heyday Films is David Heyman's production company. The second film added in a German company, MIRACLE Productions GmbH & Co. KG, which never did anything else. And on top of providing effects for all the films, the eighth also had Moving Picture Company co-produce.
 * Many blockbusters in The Eighties were this. It started majorly with Star Wars, which had an American studio, director and parts of the cast, but was shot in England with an English crew and using British actors for minor roles and with post-production split between the two. Other films that applies to this model were the first Indiana Jones films, Aliens, Who Framed Roger Rabbit? and Batman.
 * Dezha vyu (1990) comedy -- Poland and USSR (just before it fell apart). A comedy about the unpredictable development of A Simple Plan: Chicago mob in Prohibition years sending their best hitman after a traitor who escaped to Odessa (where he runs a smuggling operation together with local criminals) -- but this being early Soviet Union, after one accident the chaos snowball rolls downhill.

Live-Action TV

 * The Grid—set and filmed on both sides of the Atlantic.
 * Five Days—produced by HBO Films and the BBC. Set in South Hertfordshire.

 * The 1996 television movie was a co-production between the BBC and Universal.
 * Because of major location filming in America, the two-parter "The Impossible Astronaut"/"Day of the Moon" is listed as a BBC America/BBC Wales co-production instead of just a BBC Wales production at the end of the closing credits.
 * K9 is a co-production between Jetix Europe and Network 10 (an Australian television channel).

 * As were The No. 1 Ladies Detective Agency, Little Britain USA and Extras. (Although Band of Brothers carries a credit for the BBC on the opening credits of the UK broadcasts, the BBC isn't mentioned anywhere on the closing credits. Or on the airings on any other channel. Or the DVDs. Or... well, you get the idea.)
