15 actors who played their own twin on TV

As the saying goes, two heads are better than one, so twins on TV shows means double the fun. At least, some of the time; other times, it’s more like that quote from Macbeth — “double double, toil and trouble.”

Many TV shows over the years have featured twins (siblings born at the same time, identical or not). In rare cases, the characters are played by two different actors, a la Sister Sister with Tia and Tamara Mowry. But it’s more likely that one actor plays the twins, thanks to the magic of camera tricks. The Deuce, which premieres this Sunday on HBO, stars James Franco as twin brothers who wind up getting into the porn trade.

Here’s a list of other notable actors who’ve done double duty.

The Deuce airs Sunday nights at 9 p.m. on HBO.
