So, this is a thing. A 'Plants Vs Zombies' movie.

Via Tracking Board:

In a move that should surprise no one, I can now confirm that an adaptation of the popular video game PLANTS VS. ZOMBIES is now in development at Warner Bros. Roy Lee will produce the feature through his shingle Vertigo Entertainment, which has had a first-look deal with the studio for the last few years. Julia Spiro and Gabriel Chu will oversee development for the studio.
