According to one obituary, he was "a twinkly-eyed handsome charmer with a shy smile and a pleasant tenor voice in carefree and inconsequential Warner Bros musicals of the forties, accompanied by Jack Carson.

"[1] Another said, "for all his undoubted star potential, Morgan was perhaps cast once too often as the likeable, clean-cut, easy-going but essentially uncharismatic young man who typically loses his girl to someone more sexually magnetic.

[9] Unbilled, he lip synced as Allan Jones sang the Irving Berlin song, A Pretty Girl is Like a Melody, in The Great Ziegfeld (1936).

[2] Independent producer-director Victor Halperin gave the actor his first leading role (under his given name of Stanley Morner) in I Conquer the Sea (1936).

According to Shipman the studio "put him on the assembly-line with Wayne Morris, Arthur Kennedy, Jeffrey Lynn, Eddie Albert, and Ronald Reagan – likeable young lugs squiring the heroine till Bogart, Cagney, or Flynn came crashing down to sweep her up.

He supported Priscilla Lane in Three Cheers for the Irish (1940) and went back to "B"s for Tear Gas Squad (1940), Flight Angels (1940), and River's End (1940).

Morgan's career received a boost when RKO borrowed him to play Ginger Rogers's love interest in Kitty Foyle (1940), a big hit.

In the words of Shipman, the films would feature "Morgan as the easy-going singer who always got the girl and Carson as the loud-mouthed but cowardly braggard-comic who was given the air.

[citation needed] Without Carson, Morgan made a Western, Cheyenne (1946), a musical My Wild Irish Rose (1947), and To the Victor (1948).

[11] Morgan made The Lady Takes a Sailor (1949) then Perfect Strangers (1950) with Rogers and Pretty Baby (1950) with Betsy Drake.

[citation needed] Morgan made films for Columbia's low-budget producer Sam Katzman, The Gun That Won the West (1955) and Uranium Boom (1956) and went to RKO for Pearl of the South Pacific (1956).

In 1959, Morgan appeared as a regular, Dennis Chase, in eleven episodes of the crime drama, 21 Beacon Street, with Joanna Barnes and Brian Kelly.

[citation needed] By 1956, he had retired from films but still made occasional appearances on television, such as the role of Chad Hamilton in the 1962 episode "Source of Information" of the short-lived NBC newspaper drama series, Saints and Sinners.

His final screen performance was on March 1, 1980, as Steve Brian in the episode "Another Time, Another Place/Doctor Who/Gopher's Engagement" of ABC's The Love Boat.

In 1983, Morgan, along with his film pal, Jack Carson, who had died in 1963, were inducted into the Wisconsin Performing Artists Hall of Fame.

He raised funds for the park, at 5107 Rosemont Avenue, by "organizing exhibition baseball games featuring celebrity friends and professional athletes".
