James Stewart is the young and naive senator battling the cynical forces of Washington. Also starring Jean Arthur, Claude Rains and Thomas Mitchell, directed by Frank Capra.
This film is also dated, but not as bad as You Can't take It With You. A film like It's A Wonderful Life still works today since it has an element of a fairytale or a tale of Dickens. In this film that takes place in the more realistic world of politics you lose that element. I still find it a bit hard to believe in Capra's insistence of the decency of the common man, but even an old cynic like me have to confess that I was moved by Stewart's performance towards the end of the film.
