Average movie rating: 86.9%
Don't let the photo above fool you: Jimmy Stewart may be one of history's most beloved actors, but he's got more than a half-dozen clunkers on his filmography. His It's a Wonderful Life wife, however, does not. In fact, none of her movies rate lower than an 80% on Rotten Tomatoes. Perhaps most surprising is that the aforementioned holiday classic isn't even considered her best film; that honor belongs to 1952's Scandal Sheet (The Dark Page), which has a perfect rating.
