In the 1920s, he played with Rudolph Valentino in The Son of the Sheik, opposite John Barrymore in Don Juan, and appeared with Lillian Gish in 1928's The Wind.

One of Love's first sound films was the part-talkie The Mysterious Island co-starring Lionel Barrymore.

In 1937, he played Henry VIII in the first talking film version of Mark Twain's The Prince and the Pauper, with Errol Flynn.

Love played the bigoted Bishop of the Black Canons in The Adventures of Robin Hood, also starring Flynn.

However, he also played gruff authoritarian figures, such as Monsieur Cavaignac, who, contrary to history, demands the resignation of those responsible for the Dreyfus cover-up, in The Life of Emile Zola (1937), as well as Don Alejandro de la Vega, whose son appears to be a fop but is actually Zorro, in the 1940 version of The Mark of Zorro, starring Tyrone Power.
