Michael Caine

One of the most beloved actors of our time, Sir Michael Caine adopted his stage name in the 50s. He officially changed his name to match his passport after being repeatedly held up by security because his celebrity real names didn’t match up.

Whoopi Goldberg

Another family who all didn’t have real celebrity names, including Martin Sheen whose real name is Ramon Antonio Gerard Estevez.
