Morgan Freeman never knows if a movie is going to be a hit. The Oscar winner has starred in numerous critically acclaimed films, but he insists he can't tell how a movie is going to be received by cinema goers until it comes out and he can never predict what will warrant a sequel. The 78-year-old actor - who is reprising his role as Vice President Trumbull in the "Olympus Has Fallen" sequel, "London Has Fallen" alongside Gerard Butler and Aaron Eckhart - told website HeyYouGuys: "I have no idea shooting a movie that, 'Oh man, this is going to go really big and they're going to make a sequel.' There's no way to know, the proof is always with the audience."
