Francis Fitzgerald "Larry" Vincent (June 14, 1924—March 8, 1975) was an American television horror host, famed for his character Seymour, who presented—and heckled—low-budget horror and science fiction movies on Fright Night on KHJ-TV and Seymour's Monster Rally on KTLA, both local stations in Los Angeles between 1969 and 1974.

He was noted for his style of criticizing the movies he presented in an offbeat and funny manner, usually appearing in a small window which would pop up in the corner, tossing a quip, then vanishing again.

[2] But before moving to Los Angeles, California, he was "Captain Starr" on WFBM in Indianapolis in the 1960s, as one of a trio of hosts, along with Harlow Hickenlooper and Curley Myers for children's programing, which showed the old Three Stooges shorts, as well as skits for an in-studio audience of children which usually ended up with pie-in-the face comedy and songs from the hosts.

From 1969 to 1974 Vincent was the host for the horror shows Fright Night on KHJ-TV and Seymour's Monster Rally on KTLA.

[citation needed] On at least occasion, Larry Vincent appeared at the University of California, Riverside campus for an all night sleep-in and science fiction movie festival.
