[12] More nasty roles quickly followed with Always a Bride (1953) where he played a Treasury Investigator who turns bad as well as Forbidden Cargo in 1954 as a smuggler and Tread Softly Stranger (1958) where he is an embezzler.

Two films he made in 1955 saw him cast in more positive roles—in March Hare he played an impoverished aristocrat riding a horse for the Derby, and in the espionage melodrama They Can't Hang Me, (which used Sidney Torch's theme music from The Black Museum for its own Title and Incidental music), he starred as a dapper Special Branch officer charged with discovering the identity of an enemy agent.

[13] Morgan's biggest screen success came when he landed the title role in the ITV series Sir Francis Drake, but parts dried up after that as he was no longer seen as "the bad guy".

The Lifetaker in 1976 had him back as the bad guy again where as a wealthy business man he plans ritualistic revenge on his wife and her lover.

As roles dried up, Morgan bought a small hotel in Hove, Sussex, and ran it for some years before becoming a property developer.
