Is Zat So?

• 1927 boxing-related silent comedy movie starring George O'Brien
• Plot (from IMDb): "Wiseguy promoter Hap Hurley (Lowe) is riding a tram when the brawny motorman gets into a fight with a lorry-driver and lays him out cold. Hurley is impressed with the motorman's fighting technique, and offers to represent him as a prizefighter. The pug's name is Ed Cowan (played by O'Brien), but he's nicknamed 'Chick'. Whenever Chick has no intelligent response (which is quite often), he falls back on his catchphrase 'Is zat so?' Until they can get a boxing bout, Hurley and Chick get jobs in a posh Fifth Avenue mansion: Hurley as butler, Chick as footman. Douglas Fairbanks Jnr, near the beginning of his career here, is very impressive as a drunken playboy. His sister Sue is bullied by her husband Robert, so Hurley and Chick teach Doug to beat up the cad. Meanwhile, as if they weren't in enough trouble, Hurley falls in love with the household's secretary, while Chick falls for the nanny who supervises Sue and Robert's bratty son Jimmy."
