I swear Rock must have several identical twins to handle his workload. Even if this tweet isn't indicative of him angling for a role, he's somehow managing to balance the lead role in a series, occasional wrestling appearances, a huge action film franchise, umpteen gazillion other movies, constant talk show appearances, charity stuff, and still finds time to tweet like he's permanently jacked into the thing.
Still, if he's interested, it might be a good idea for the producers to have a chat with him.
