Question: What type of entertainment does Four Star Playhouse and David Niven have in common?

Context paragraphs:
Mr. Lucky (TV series): Mr. Lucky is a CBS adventure/drama television series that aired from 1959 to 1960 with repeats until September 3.  Blake Edwards developed the program as a retooling of his Willie Dante character from "Four Star Playhouse", in which the role was played by studio boss Dick Powell.  In the 1960–1961 television season, Howard Duff assumed the role of Willie Dante in the NBC adventure/drama series "Dante".  John Vivyan played "Lucky", not "Dante".

Four Star Playhouse: Four Star Playhouse is an American television anthology series that ran from 1952 to 1956.  Four Star Playhouse was owned by Four Star International.  Its episodes ranged anywhere from surreal mysteries, such as "The Man on the Train," to light comedies, such as "The Lost Silk Hat."  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.

Four Star Playhouse (radio program): Four Star Playhouse was a radio dramatic anthology series in the United States.  The 30-minute program was broadcast on NBC beginning in July 1949 and was sustaining.  It lasted only three months.

My Fair Lady (1958 TV series): My Fair Lady was an Australian television series which aired from 1958 to 1962 on Wednesdays on Melbourne station HSV-7.  Little information is available on this series.  It was originally part of a line-up titled "Home", which featuring various segments including "Cooking", "Home Decorator" and "Shopping Guide".  Later, it appears the "Home" branding was dropped.  For part of its run it aired at 2:30PM.  At one point in 1959 it was the first show on the station schedule for the day (this was prior to Australian television being a 24-hour service), while at another point in 1959 it was preceded by US anthology series episodes of shows like "Four Star Playhouse".

Anthology series: An anthology series is a radio or television series that presents a different story and a different set of characters in each episode or season/series.  These usually have a different cast each week, but several series in the past, such as "Four Star Playhouse", employed a permanent troupe of character actors who would appear in a different drama each week.  Some anthology series, such as "Studio One", began on radio and then expanded to television.

Chevron Hall of Stars: Chevron Hall of Stars is an American television anthology series which aired in 1956 in first-run syndication.  Information is somewhat scarce on the series.  It was produced by Four Star Productions, and was a half-hour series.  Four Star's other mid-1950s anthology series ran about 25 minutes excluding commercials (as can be seen of episodes of "Four Star Playhouse" and "The Star and the Story" on the Internet Archive), which was likely also the case with "Chevron Hall of Stars".  Confusingly, in some areas the episodes aired under the title "Stage 7", which had also been a series in 1955.  Gene Roddenberry’s script "The Secret Weapon of 117" aired as part of the series.

David Niven: James David Graham Niven (1 March 1910 – 29 July 1983) was an English actor, memoirist and novelist.

He also made five guest appearances on "Perry Mason", including two roles as murder victims: John Callender in "The Case of the Fan Dancer's Horse" (1957), and Ken Bascombe in "The Case of the Bashful Burro" (1960).  He also had eight appearances on "Rawhide", four on "Bonanza", and four on "The Fugitive".
