The three actresses who look most alike are Emily Watson, Miranda Otto, and Emily Mortimer. I can't tell the difference between them. In fact, if someone told me it was the same actress who doesn't want to risk overexposure, I'd look skeptically and say, "Really?"
The two actors who look most alike are Christopher Meloni and Elias Koteas. If I see one of those guys in a movie, I'd ask if that's the guy from one of those detective shows or if it's the guy from that other war movie.
That's right. That's the end of this message. When I get some free time, I'm going to do a lengthy comparison of mountain bike trails in St. George and Moab. It's surprisingly close.
