We know Leonardo DiCaprio's pretty passionate about wildlife, seeing that in the past he's donated $1 million to the World Wildlife Fund and has tweeted extensively about saving tigers. Now, the actor has recruited a few good men to aid him in his mission.

Tobey Maguire and Tom Hardy are on board to help DiCaprio develop a film about poaching over at Warner Bros., a rep for the studio told CNN. As of now, there aren't any additional details or acting attachments lined up.

A rep for Maguire tells CNN that the three stars have just "the very beginnings of an idea" at the present time.
