Eddie Redmayne was so nervous at this year's (16) Comic-Con event in San Diego, California Colin Farrell had to calm him with a back rub.
The actors play rivals in new Harry Potter spin-off Fantastic Beasts and Where to Find Them, and promoted the film together at the fan convention in July (16).
Eddie, who portrays magical beast expert Newt Scamander in the upcoming wizarding movie, was attending his first Comic-Con as the face of a major franchise, and the 2015 Oscar winner admits he was spooked by the 6,000 adoring fans who showed up for the cast's panel discussion.
"I'd heard from friends what the experience was (like), but I had no idea how big it would be and I was chronically nervous to the extent that I had Colin Farrell giving me a back rub and whispering sweet nothings into my ear, trying to calm me down," he tells British chat show host Graham Norton. "You go on in front of thousands of people and you feel like a wannabe Justin Bieber!"
But having won one Academy Award for Best Actor and finding himself among the nominees again this year (16), Eddie admits he's starting to notice the effects of global fame.
"I had a weird moment on the tube (London Underground)," he explains. "I was sitting there and suddenly a (camera) flash goes off from the person opposite me. I looked up, they looked at me and I looked at them and then there was a really awkward 47 seconds as I waited for the next stop and dashed off."
Fantastic Beasts and Where to Find Them, based on the book by Harry Potter author J.K. Rowling, is released next month (Nov17).
