Holocaust denial is the act of denying the genocide of Jews and other groups in the Holocaust during World War II.
The Three Stooges appeared in 220 films through their career. Of those 220, 190 short films were made for Columbia Pictures, for which the trio are best known today. Their first Columbia film, Woman Haters, premiered on May 5, 1934. Their contract was extended each year until the final one expired on December 31, 1957.
Short answer: Moe, Larry, Curly, Shemp, Joe, Curly Joe. 6. Moe and Larry were there for the Stooges' entire film career, but the position of the third Stooge was filled by several people. After Curly left the act, Shemp played the part, and after Shemp, there was Joe, and finally Curly Joe. That makes six.
