Domhnall Gleeson has one pretty amazing doppelgänger. 

The About Time star revealed that he's been told he looks like Cate Blanchett since he was a teenager and that their first meeting was utterly, hilariously awkward. 

"When I was 19, I did my first job. I did a Martin McDonagh play," he recalled on The Late Show With Stephen Colbert on Thursday. "People used to call me Cate all the time. My whole cast called me Cate because I looked really like Cate Blanchett when I was 19 years old."
