An attempt was made to adapt
A Day in the Life of Dennis Day as an
NBC filmed series (
Sam Berman's caricature of Dennis was used in the opening and closing titles), produced by
Jerry Fairbanks for Dennis' sponsor, Colgate-Palmolive, featuring the original radio cast, but got no farther than an unaired 1949 pilot episode. In late 1950, a sample
kinescope was produced by Colgate and their ad agency showcasing Dennis as host of a projected "live" comedy/variety series (
The Dennis Day Show) for
CBS, but that, too, went unsold. He continued to appear as a regular cast member when
The Jack Benny Program became a TV series, staying with the show until it ended in 1965. Eventually, his own TV series,
The Dennis Day Show (or
The RCA Victor Show), was first telecast on NBC on February 8, 1952, and then in the 1953–1954 season. On this show, Day played a less-fictionalized version of himself, using his natural voice and behaving as an adult who was considerably more mature than his Benny character. Between 1952 and 1978, Day made numerous TV appearances as a singer and actor (such as NBC's
The Gisele MacKenzie Show, ABC's
The Bing Crosby Show and
Alfred Hitchcock Presents) and voice for animation. Day appeared as the "Mystery Guest" on the January 23, 1955 episode of ''
What's My Line?''. Day was correctly identified by panelist
Dorothy Kilgallen. In 1957, Day played himself in episode seven, season two of the briefly aired (1957–1958) situation comedy called
Date with the Angels in which, on the way to a recording studio, Day's car breaks down in front of Vicki Angel's (
Betty White) home. While waiting for the automobile service to arrive, he does a few imitations (including
Elvis), sings a song, and does a duet with Vicki. The episode, which began in
Sardi's restaurant, included brief appearances of
Liberace and
Hugh O'Brian. While numerous stars appeared in the series without credit, all three (Day, Liberace, O'Brian) guest stars appear in the credits on that episode. He also appeared in
Date with the Angels – season one, episode 13, as himself; it aired on Friday at 9:30 pm, October 25, 1957, on ABC. Some records show it was episode 19, titled "Star Struck". During the final season of
The Jack Benny Program (1964–65), Day was nearly 49 years old, although Benny was still delivering such lines as "That crazy kid drives me nuts ..." His last televised work with Benny was in 1970, when they appeared in a public-service announcement together to promote savings and loans. This was shortly after the whole cast and crew of
The Jack Benny Show had joined for ''Jack Benny's Twentieth Anniversary Special''. He starred as railroad employee Jason Barnes in the 1962
Death Valley Days TV episode "Way Station". In 1972, he co-starred with
June Allyson and
Judy Canova in the first national tour of the Broadway musical
No, No, Nanette. In 1976, Day was the voice of Parson Brown in the Rankin-Bass production ''
Frosty's Winter Wonderland and again worked with them in 1978, when he voiced Fred in The Stingiest Man in Town'', which was their animated version of
Charles Dickens' novel
A Christmas Carol. Day was given stars on the Hollywood Walk of Fame for radio and television in 1960. ==Film==
