Celebrity Look-Alikes Who Will Have You Seeing Double

If you’re not celebrating 420 today, then we have an alternative holiday for you: National Look-Alike Day!

As you probably know, there are quite a few Hollywood stars who look so strikingly similar, it’s easy to get them confused. Isla Fisher and Amy Adams get mistaken for one another lots thanks to their gorgeous red locks, but neither one of them agrees with the comparison. Meanwhile, put Javier Bardem and Jeffrey Dean Morgan side by side and you’ll swear you’re seeing double. Brunette beauties Katy Perry and Zooey Deschanel have been known to trip people up. And Elizabeth Banks and Chelsea Handler bear such a striking resemblance, even they joke about being twins.

Check out this video for a look at some of our favorite celebrity look-alikes, and tune in to The Insider With Yahoo on TV tonight for the latest in entertainment news.
