I have to tell on myself here.
I don't follow celebrities. At all. As in, I get a basic understanding of them from covers of magazines at the checkout aisle. As such, older famous people pretty much escape me. I also don't watch movies too often. My sister teases me often for this.
So the Sprint commercials started with James Earl Jones and Malcolm McDowell. That's great, I recognized James Earl Jones by voice, and knew the other guy was famous for something. Sis watched me watch the commercials, then saw me struggling with the name of the second guy. She provided me his last name, and the only thing I could think of, I knew was wrong. I said so, and she said to try anyway.
Apparently she got quite amused when I said Roddy McDowall. She nearly passed out laughing at me. Her boyfriend gave both of us a strange look, then said "Malcolm. Malcolm McDowell. Close, but no cigar."
I mean, their last names sound identical in my neck of the woods, they're both British actors, and I'm known for not being up on celebrities and such. I'm reminded of this every time I go into the Commercials You Love thread and there's a conversation about those commercials.
