Cast Them As Siblings!

Pairs of actors that look and/or sound alike and could be cast as siblings.

Apparently people need directions on how to read this list. Read the comments beside the photos for some of them. The actors and actresses are placed in order, so that their pictures are above or below the person who looks eerily similar to them. Obviously I am not suggesting Sanaa Lathan and Dermot Mulrooney should be cast as siblings. Use a little common sense, viewers.

Brad Pitt
An actor and producer known as much for his versatility as he is for his handsome face, Golden Globe-winner Brad Pitt's most widely recognized role may be Tyler Durden in Fight Club.

“ Brad and Matthew would probably make for an odd pairing. But they both have that twinkle in their eyes and a mischievous grin when the mood strikes. They would play the kinds of siblings that got into trouble a lot. You'd probably need a straight man third sibling for them to work. ” - elizdere
