Before he began working on the Song of Ice and Fire series, George R.R. Martin worked as a television writer for show likes The Twilight Zone. He originally quit television because he wanted to work on a project free from the concern about whether or not something was filmable which is ironic considering the popularity the Song of Ice and Fire series has gained since being adapted for TV.
