Fraternal twins Kyle and Peter accidentally discover they've been living with a lie all their lives. more
Owen Wilson and Ed Helms star as fraternal twins Kyle and Peter who accidentally discover they've been living with a lie all their lives. The kindly man in the photo on their mantle isn't their father after all, but an invention their mother (Glenn Close) concocted to conceal the truth: that she actually doesn't know who their real father is. See, it was the seventies, and things were crazy, and...well, you know.
