Clinton Charles Sundberg was a stage and film character actor.
Clinton Sundberg was born in Appleton, Minnesota the son of Grace A. Coffey Sundberg. His birth year has been disputed with sources differing between 1903 and 1906. The Internet Movie Database and Internet Broadway Database claim 1903, while Allmovie states 1906, which is supported by The New York Times and The Los Angeles Times obituaries, which reported his age as 81. However the Social Security Death Index and the 1910 United States Census both confirm 1903.
Sundberg left teaching for acting and appeared in a number of Broadway plays. His most notable roles were Mr. Kraler in the original 1957 production of The Diary of Anne Frank and Mortimer Brewster in the 1944 Arsenic and Old Lace. He had numerous supporting roles in films of the 1940s and 1950s. He played Mike, the bartender who listens to Judy Garland's character's troubles in Easter Parade. One of Sundberg's most memorable roles was in the 1949 Metro-Goldwyn-Mayer film In the Good Old Summertime, in which he played the part of Rudy Hansen, a friendly co-worker and confidante of Johnson's character.
