1. Christian Slater
In real life: The star of Pump Up The Volume, Heathers and True Romance, Slater hasn’t exactly been enjoying a career high for the last few years.
His movie work has been patchy and the recent TV show he hoped would give him a boost (My Own Worst Enemy) spluttered to a halt with only nine episodes aired.
In Star Trek: Slater crops up in Star Trek VI as an unnamed Communications Officer aboard the Excelsior who is charged with the massively important task of, er, waking up Captain Sulu.
What, Sulu doesn’t have an alarm clock or a communications unit in his quarters?
Did you know? Slater is a massive Trek fan that, as a child, once shaved his eyebrows so he could look like Spock. They never grew back properly.
And who did he turn to for his quick moment in the film? His Mum. No, really: Mary Jo Slater was the casting director on The Undiscovered Country. Nepo-tastic!
