Amy Adams and Isla Fisher look so alike that they probably use each other as doubles when it's convenient for them. If Adams can't make red carpet or interview appointment, she can send Fisher in her place, or vice versa, and nobody will be any the wiser. Wouldn't it be nice if you could send your own double to work in your place occasionally?
The resemblance between the two is so striking that even people who work in the industry struggle to tell them apart. Fisher told Jimmy Kimmel that she was once approached at an Oscar Party by Lady Gaga, who started complimenting her for Adams' work in 'American Hustle'. Fisher found the whole experience so awkward that she didn't even try to correct Gaga; she just bowed her head and accepted the praise gracefully. We get it. Who wants to make Gaga feel embarrassed? Not us!
