Who Killed Doc Robbin?

Young Curley Benson (Larry Olsen) and his buddies have their hands full when an eccentric scientist (George Zucco) is believed killed in a lab explosion--and their repairman pal (Whitford Kane) gets arrested for murder as a result. Looking for proof of his innocence, the kids invade the disagreeable doctor’s creepy mansion...and get stalked by his pet gorilla! Second and final "Curley" feature from Hal Roach co-stars Virginia Grey, Eilene Janssen. AKA: "Curley and His Gang in the Haunted Mansion," "Haunted Mansion," "Sinister House."
