He had 20 other credits in 1957 aside from "Doomsday" for SUSPICION, including his first full-length crime feature, THE GREEN-EYED BLONDE. He hooked up with Hitchcock again when the AH HOUR began, and became one of the featured directors for that show during the first season (1962-63). He capped his involvement there with the 1964 episode "Water's Edge," one of the peaks of the series, featuring stellar work from Ann Sothern and John Cassavetes.
He had an interesting career as a feature film director in subsequent years, following up THE GREEN-EYED BLONDE with the frenetic THE PARTY CRASHERS (1958). He made an intriguing semi-documentary "inside government noir," A PUBLIC AFFAIR (1961), a bit overly earnest in its approach but "saved" by an appearance from cult actress Grace Lee Whitney (later of STAR TREK fame), and his subsequent feature work is not without interest: DEAD HEAT ON A MERRY-GO-ROUND (1966), and THE MAD ROOM (1969, a updated remake of LADIES IN RETIREMENT with Stella Stevens)
His hand can be discerned in the Gothic romp WHATEVER HAPPENED TO AUNT ALICE? (also 1969, where he is uncredited but was brought in by producer Robert Aldrich to boost several key sequences). Alas, Girard's career went off the rails in the early 70s and he found himself taking early retirement shortly thereafter...but he left a lot of interesting material to rediscover.
