4. David Schwimmer
Six Days Seven Nights David Schwimmer has thankfully worked behind the scenes for most of his career, and in his minor roles hasn't really affected the overall product. He was briefly in the excellent "Band of Brothers," and co-starred in the underrated "Uprising," but his most uninspired and terrible role was as the heel boyfriend in the mediocre adventure comedy "Six Days and Seven Nights" as Anne Heche's adulterer boyfriend who hooks up with Harrison Ford's girlfriend as Ford and Heche find themselves in the jungle.
