Emily Blunt often forgot her lines while shooting upcoming horror THE WOLFMAN - because she was so in awe of her co-star SIR Anthony Hopkins.
The British actress became pals with the legendary Oscar-winner after he invited her over to his trailer at the beginning of filming for a dinner of baked potatoes.
But despite their friendly ways, Blunt admits she couldn't help but look on in wonder as he acted - much to the detriment of her own performance.
She says, "He invited me over for baked potatoes topped with baked beans and cheese to talk about our characters. So we were pals.
"He's very cool. He's the best. I was riveted by him. I just followed him around like a lovestruck teenager. I would sit around and talk to him between takes and he'd tell us wonderful stories. He is very wise, very open and incredibly kind. He hasn't lost that childlike enthusiasm for creating a part. He's quite an economical actor. It's masterful to watch - and it's distracting. I'd watch him in the scene and then think, 'Oh, s**t! I forgot my line.'"
