Jack Quaid

The 'Oppenheimer' actor is the son of film stars Dennis Quaid and Meg Ryan and only realised that his Tinseltown upbringing had been unique once he got older.

He told People recently: "I grew up with friends who also had parents in the industry, so it didn't really feel different.

"But then you grow up, and you realise that's a pretty unique thing, that not one but two of your parents are actors. You don't realise that things are slightly abnormal until later."
