Romances between partners of vastly different ages have always been a cornerstone of Hollywood legend. Humphrey Bogart and Lauren Bacall are a classic example: their 25 year age difference (she was 20, he was 45 and had been married three times before) didn't stop them from falling, and staying, in love. Bacall described their relationship as “the headiest romance imaginable." They married in 1945 and and stayed together until Bogie's death in 1957.

Charlie Chaplin and his future wife Oona O'Neill (daughter of playwright Eugene O'Neill) first met when he was 53 and she was 17. He'd already been married three times, twice to 16-year-olds. O'Neill explained their relationship: he "made me mature, and I keep him young."
