GENE SISKEL
Gene Siskel was a famous film critic from the 1960s to the 1990s. He is best remembered as the co-host (alongside Roger Ebert) of "Sneak Previews" (later "Siskel & Ebert At the Movies") which was a long running television talk show in which current movies were previewed, discussed, and critiqued (and the two hosts gave "thumbs up" and "thumbs down" to each movie). Siskel passed away in 1999 at the age of 53 from brain cancer.
