She looked good in the shower scene though. I too only saw the movie after being familiar with the TV series. I thought (and still think) the subject matter works better as a comedy (war is too horrific already) and the last half of the movie is a stupid football game.
Kellerman had a few other good roles (Brewster McCloud, The Player, The Big Bus, Welcome to L.A.) but she was no Loretta Swit.
