When I read that Rex Reason, a...

..."dashing movie star" died at age 86, I thought: Okay, what was this guy's real name?

From his obit in the Times (my emphasis):

Oddly, for an actor with a name made for Hollywood, Universal insisted that he change it to Bart Roberts when he appeared in “Taza, Son of Cochise” and “Yankee Pasha” in 1954. But he demanded to use his real name again starting with “This Island Earth.”

It's my Name of the Day.
