I'm thinking of some of the TV series nowadays that are spinning off film franchises (this question was prompted by the Dune prequel series), and wondering if there were ever TV series "bets" that didn't pan out because the movie tanked.
I'm told this isn't enough text, so let's briefly imagine: "I did nahhhhhttt. Oh hi Mark audience laughter 'The Room' is filmed before a live studio audience."
Copied from the Van Helsing wiki:
In April 2004, a month before Van Helsing opened in theaters, they announced they were greenlighting a television series titled Transylvania. The plan was to use the set from the original film, and Universal Studios paid to maintain the structures so that they could return to film there, and the series was planned to premiere on NBC in the fall of 2004. However, just two weeks into Van Helsing's release, the studio canceled the plans for the television series.
