If you want to create a TV show, there are tons of ways to find inspiration. You can go the modern route and look to the printed page to find the next Game Of Thrones. You can even make a sequel to an old show and pretend people will still care. If you want to be a dick about it, you can sit around writing an original script that's based on an original idea and make an original show. But, that's stupid.
Or, you can attempt to pull off what might be one of the most difficult challenges in all of Hollywood: turning a movie into a good TV show. It's often attempted, rarely successful. As you read this, there are dozens of movies being turned into TV shows. But, judging from the track record, the best most of those shows can hope for is ending up as a two-sentence-long subsection on the original movie's Wikipedia page. Most are so embarrassingly bad they're instantly forgotten. However, you can't run from the Internet. It knows all the embarrassing shit you would rather forget, including Hollywood's numerous failed attempts at pulling off the movie-to-TV adaptation.
I can only hope all upcoming TV adaptations aren't as forgettably bad as ...
5Clerks: The Sitcom
In the middle of filming Mallrats back in 1995, Kevin Smith found out that casting was underway on the TV version of his classic indie comedy Clerks. Up until that moment, he had no idea anyone had been adapting the movie he wrote, produced, directed, and edited -- into a TV series.
He's Silent Bob, not Deaf-Mute Bob.
A pilot episode was eventually shot. It didn't include a single member of original film's cast, and the characters are all cleaner and more TV-friendly, making them the harder-to-relate-to versions of their film counterparts. Smith's patented vulgar, snappy dialogue that feels like it would be more at home in a stage play performed in a middle-school-aged boy's bathroom is gone, replaced with generic sitcom setups and punchlines so weak the only way to tell someone had told a joke is by waiting for the inevitable cue of canned laughter.
Everything that felt fresh and original, and even revolutionary, about Smith's movie was burned to the ground and replaced with a strip mall. It's a perfect example of what happens when you take a small, crude, underground voice and point of view and try to sanitize it for mainstream audiences. After hearing about the show, Smith tried to take part by writing a script for an episode ... which was rejected by the producers. Though, even if they did like it, it's not like his script would ever been shot. The show never made it past its pilot episode. Watch it, and you'll see why:
4Casablanca (1955) and Casablanca (1983)
Whenever film buffs try to quantify the "best film of all time" debate, Casablanca ends up somewhere near the top of the list, along with Citizen Kane and City Slickers II: The Legend Of Curly's Gold. It's widely considered one of the finest examples of filmmaking and screenwriting ever produced, so, of course, TV producers thought they could replicate Casablanca's lightning-in-a-bottle level of quality for the length of an entire TV season. Twice.
The first attempt at a TV adaptation was in 1955, 13 years after the movie's release. A lot of the actors who had played minor characters in the movie were brought back to play larger roles in the show. In the film, Marcel Dalio played a small part as the operator of a roulette table. In the show, he got bumped up to the role of Captain Renault, one of the most important characters in the story. The show was a prequel to the movie, and it only lasted 10 episodes before people realized they didn't want to watch Casablanca for 10 hours.
The proof that humans are constantly teetering on the edge of insanity by doing the same dumb things over and over and expecting different results comes in the form of the second Casablanca show, this one from 1983. If the '80s show had bet the '50s show that it could get canceled in five less episodes, it would have won. By this point, the movie had been canonized as one of the greatest ever. Generations had grown up with it in their lives. The 1984 attempt at a show didn't stand a chance. It didn't help that, like the '50s Casablanca show, this one was also a prequel, taking place about a year before the events of the movie.
Prequels are the coward's sequel.
