Andrew Garfield humiliated himself when he was introduced to Christopher Lloyd - he turned into a "screaming schoolgirl" upon meeting the Back To The Future legend.
The British actor was left completely starstruck by Lloyd and now regrets losing his cool in the presence of his idol.
He tells MTV.com, "I met Christopher Lloyd. I lost my mind. I turned into a schoolgirl. I started screaming in his face. I went insane. But I guess because his performances had such a profound effect on me, it was like meeting a hero."
But Garfield, who is set to play Spider-Man in the upcoming superhero reboot, hopes his movies won't attract any hysterical fans.
He adds, "I personally haven't been on the receiving end of that, thankfully. Maybe naively, I think my life is going to stay the same in terms of anonymity (after playing Spider-Man).
"I feel it's so important to have a normal life, to be able to walk down a city street and have a normal human experience in order to reflect that in the work. Otherwise, you can't relate. It's so funny how actors are perceived. It's craziness."
