Conrad continued as Dillon after the TV show had
already started, and played the role until 1961. He
was considered for the role of Dillon on the TV show,
but the creators and producers decided, in the end,
to go for Arness in his place. It’s rumored that his 
weight was a factor behind his not being cast.
