Simon Pegg has opened up about his co-star Tom Cruise and insists he's "far more human" than his public persona.  The actors star alongside each other in Mission: Impossible - Rogue Nation and Simon has now shrugged off the "mythology" surrounding Cruise. Simon says Tom is "very fun" and "kind of vulnerable".  Speaking to E! Online, the actor revealed: "I love Tom. I love working with him because he's a really interesting person. I feel really privileged to get to see the real man, you know? "There's a lot of mythology about him, a lot of speculation about the kind of myth that surrounds him that people are very keen to believe." The pair starred alongside each other in Mission: Impossible 5.  "When you actually meet the man himself, he's different. He's far more human. He's very fun. He's kind of vulnerable, and he's a human being, and it's great to see. "But he can also be Tom Cruise when he wants to be. I say to him, I say, 'Do Tom Cruise.' And puts his sunglasses on and smiles. 'There's Tom Cruise!' And he knows it! It's a brilliant capacity to have." The star is reportedly dating his assistant, Emily.  Simon's comments come amid reports that Tom "banished" his niece from the family after "making out" with a boy. In a YouTube video uploaded by scientologist Nick Lister, the Cocktail actor is accused of sending his niece across the country to Missouri and keeping her from family functions.
