The NBC annual tradition continues as the iconic 1946 film once again returns to primetime. Directed by Frank Capra, “It’s a Wonderful Life” stars Jimmy Stewart as George Bailey, a discouraged and despairing savings and loan manager who contemplates suicide before a guardian angel, Clarence (Henry Travers), intervenes and allows him to see what his small town of Bedford Falls would be without him — and all that is right in his world.
