Chiwetel Ejiofor couldn't cope with Benedict Cumberbatch's level of fame.
The 38-year-old actor - who stars alongside the Brit in Marvel's new comic book movie 'Doctor Strange', which is due out next year - has revealed he has no desire to become more famous than he already is.
He said: "This is something that I'm very grateful for, but on the whole, people are very respectful with me.
"They're nice, and they ask for an autograph or photograph, and it very rarely has any kind of hysterical quality to it. That's the thing I don't respond very well to, and I see it very often with friends of mine."
And to underline his point, Chiwetel cited the example of his 'Doctor Strange' co-star, who is among the most sought-after actors in Hollywood.
He told Vulture: "For example, I'm working with Benedict Cumberbatch at the moment, and people have that quality when they're around him. They get a little hysterical about it, and that is really odd to watch. To be in the centre of that is very peculiar."
Chiwetel insisted he's "glad" he doesn't receive such adoration.
He said: "Each actor influences the people who go to see their movies in totally different ways. It's fascinating to see that distinction in action, but I'm sort of glad it's not something I contend with."
