It’s difficult to follow someone else in a role, but Robin Curtis was called upon to do so in Star Trek III: The Search for Spock.
It may have been hard to follow someone in a role, but at least Curtis had an easy audition experience due to Leonard Nimoy. “I remember the process very, very, very clearly,” she said. “I interviewed with the casting people. That really wasn’t an audition, because there was nothing to read. Almost a day to two days later I met Leonard Nimoy one-on-one. That was first time I read any sides, as it were, from the script. I did not audition again until the screen test. So it was the gentlest experience.”
