Matt Damon might be an Oscar winner, renowned philanthropist, and the face of a multi-million dollar action franchise, but at home, he's just Dad.
"I try to tell them [how cool I am]," Damon joked to ET at the Toronto International Film Festival on Saturday. "My wife doesn't really even get that either. But that’s alright. I’ll keep them around."
In his upcoming film The Martian, Damon plays an astronaut who has to survive after being stranded on Mars. It’s a recurring theme for the actor, who has also played left-behind characters in Interstellar and Saving Private Ryan.
"It's a theme, you know," he laughed. "In this movie they come to get me, Saving Private Ryan they come to get me, I'm repeating these themes, I guess. Or I'm just very leave-able. I'm not quite sure which."
Damon said his family, which includes wife Luciana, the couple's three daughters and Luciana's daughter from a previous marriage, is the one thing he would want to have with him if he were really stuck in space.
Most of Damon's kids haven’t seen more of his more grown-up work, and the actor admits that "my younger ones have basically seen Happy Feet 2 and Spirit, which is a movie I did a long time ago." But he and his wife were able to bring their 17-year-old daughter to Toronto to see The Martian.
"She loved it," Damon told ET proudly. "The movie is like a love letter to science. It's a very optimistic, hopeful, uplifting movie. She was into it."
