Four Star Playhouse is an American television anthology series that ran from 1952 to 1956, sponsored in its first bi-weekly season by The Singer Company; Bristol-Myers became an alternate sponsor when it became a weekly series in the fall of 1953. The original premise was that Charles Boyer, Ida Lupino, David Niven, and Dick Powell would take turns starring in episodes. However, several other performers took the lead from time to time, including Ronald Colman and Joan Fontaine. Blake Edwards was among the writers and directors who contributed to the series. Edwards created the recurring character of illegal gambling house operator Willie Dante for Dick Powell to play on this series. The character was later revamped and spun off in his own series starring Howard Duff, then-husband of Lupino. The pilot for Meet McGraw, starring Frank Lovejoy, aired here, as did another episode in which Lovejoy recreated his role of Chicago newspaper reporter Randy Stone, from the radio drama Nightbeat.

This historical drama tells the story of the first class to graduate from the U.S. Military Academy at West Point. In the early 19th Century, Congress appropriated the money to build the school, but opponents who believed it to be an illegitimate expansion of the powers of the federal government decided to sabotage the school. They put the hard-as-nails Major Sam Carter in charge of the academy, and he ruthlessly put the recruits through grueling training -- until only ten prospective soldiers remained. They include Dawson, a patriotic farm boy and Howard Shelton, a selfish playboy who has come to West Point only because of its prestige. The two vie for Carolyn Bainbridge, while they, along with the other eight, try convince Carter that the school is worth keeping.

When American newspaperman and adventurer Henry M. Stanley comes back from the western Indian wars, his editor James Gordon Bennett sends him to Africa to find Dr. David Livingstone, the missing Scottish missionary.

In 1915 France, Major Brand commands the 39th Squadron of the Royal Flying Corps.

Insubordinate air ace Captain Courtney is another thorn in Brand's side...but finds the smile wiped from his face when he rises to command the squadron himself. Everyone keeps a stiff upper lip.

Lady lawyer Portia Merryman (Frieda Inescourt) defends woebegone Elizabeth Manners (Heather Angel), who is on trial for shooting her lover Earle Condon (Neil Hamilton). Ironically, Portia herself had once had a relationship with Earle Condon, but Earle's father, powerful publisher John Condon (Clarence Kolb), forced them apart. She has a pretty good idea of what is going on in Elizabeth's head, since she herself was on the verge of killing Earle Condon when his father ruthlessly took custody of her illegitimate son. As Portia toils and strains to free her client, she carries on a romance with Dan Foster (Walter Abel) -- the attorney for the prosecution. LA Law and The Practice have nothing on this one!
