Torn Curtain (1966) - Hitchcock's cameo
Hitchcock's cameo in Torn Curtain (1966) occurs about 8 minutes into the film.
Hitchcock is sat in the Hotel D'Angleterre ("English Hotel") foyer nursing a small child. From the way he holds the child up, it would appear that someone might have just had a little accident!
