Which Lego Theme would you like to see as a Theatrical Film?

Doesn't necessarily have to be animation, can be live action but inspired by the lore of a specific Lego theme. Adventurers or a modern Castle film based around the Lion Knights, Black Falcons, Wolfpack etc would be sick in my opinion. Monster Fighters and Alien Conquest too. Althought I'm sure Bionicle would be a popular choice.
