Actor George Clooney was "embarrassed" going out with dyed hair.

The 54-year-old, who is married to lawyer Amal Clooney, is known for his silvery hair and worried what people thought of him when they saw him sporting much darker hair while filming comedy `Hail, Caesar!`.

`After I'd wrap I'd change into normal clothes and I'd go to dinner with my wife and people would see me with black hair and they'd be like 'Really, dude? Really?' I'm like, 'It's for a movie',` eonline.com quoted Clooney as saying.

"They thought I was that guy. It was a little embarrassing,` he added.
