Alan Hewitt (January 21, 1915 – November 7, 1986) was an American film, television and stage actor.
Born in New York City, Hewitt was educated there and entered Dartmouth College when he was 15, graduating in 1934. His acting debut was in a school production at age 10.
Hewitt first appeared on the New York stage in The Taming of the Shrew in 1935, starring Alfred Lunt and Lynn Fontanne. He later toured with them in that play. His obituary in The New York Times noted that he "scored his biggest successes on Broadway in William Saroyan's Love's Old Sweet Song and John Steinbeck's Moon Is Down." in 1936-37, he appeared again with Lunt and Fontanne in productions of Amphitryon 38 and The Sea Gull.
Among the movies Hewitt appeared in are A Private's Affair, That Touch of Mink, Days of Wine and Roses, How to Murder Your Wife, Sweet Charity, and The Barefoot Executive.
He never became a major star, but he did have a lengthy career which included smaller parts in several well-known programs, including Alfred Hitchcock Presents , Maverick , 77 Sunset Strip Daktari, Leave It to Beaver, The Donna Reed Show, Dr. Kildare , Bewitched , I Dream Of Jeannie , The Lucy Show , F Troop , The Wild Wild West , Ironside , The Bob Newhart Show and The Phil Silvers Show. He made four guest appearances on Perry Mason, three of which he portrayed the murderer: in 1961 he played Bruce Sheridan in "The Case of the Wintry Wife" and Dr. Marcus Tate in "The Case of the Brazen Bequest," and in 1965 he played the role of Curt Ordway in "The Case of the Fatal Fetish". Possibly his most prominent roles were Detective Brennan in My Favorite Martian and the district attorney in How to Murder Your Wife.
