The cast of Apollo 13 learnt to deal with zero gravity, a feat which only real astronauts would normally get to master. Maybe one day, when the rst package holiday trips to the moon are launched, they can take advantage. Redford and Brad Pitt, meanwhile, learned to flysh for A River Runs Through It. Those empty hours between takes must just whizz by now. As long as they're near a river.
Some new experiences are less welcome, however.
Richard was sick as a dog and hasn't drunk booze since, but he must have learnt something, judging by that performance. It's no pain, no gain in the ruthless world of movie-making. Ever since De Niro porked out for Raging Bull, misguided luvvies have come to believe that your talent as an actor can be judged by how successfully you can do something totally unnecessary, preferably health-threatening, to prepare for a role. Besides, you suspect some actors are picking their roles just to learn glamorous tricks. Look at Tom Cruise.
