VIDEO Vin Diesel's The Last Witch Hunter looks insane

More than most in Hollywood, Vin Diesel is an actor who seems to have persisted mainly through force of will.

Less than gifted when it comes to performing, he's instead forged an entire career by playing people who sounds like they chew gravel for breakfast. He even took this to its logical endpoint by playing an actual sentient tree with a single line of dialogue as Groot in Guardians of the Galaxy.

You can't fault the 48 year olds ambition, especially the drive which helped to revitalise the flagging Fast and Furious franchise - he came on board as producer for 2009s Fast and Furious when the series started to turn itself around. So whenever he has a new project on the boil, it might just be the next big thing.
