Sounds fair.
I just completed the final mission (spent ages gliding around trying to kill Ravello with C4 as i ran out of bullets; ended up just grappling him into a rock), and i was listening to the propaganda minister for the last time. Throughout the whole game, every time he piped up i though "Man does that sound like David Tennant" But i assumed it couldn't be him. Just Cause 3 is a big game, but they don't usually get big actors in, especially to do such a small part...
And what do you know, it fucking is!
