Castor Oyl is a
cartoon character[?] created by cartoonist
Elzie Segar[?] for his
comic strip Thimble Theater, which was later renamed "
Popeye". Castor Oyl is
Olive Oyl's brother. He was the main protaganist of Thimble Theater for years before the first appearance of the Popeye character. Castor Oyl continued to be an important character in Segar's Popey strip, but played little (most usually no) role in the
movie animated cartoon Popeyes produced first by
Fleischer Studios and then by
Paramount Pictures.
