VInce Vaughn, who called north suburban Lake Forest home before becoming a famous actor, jumped from a plane Saturday at Chicago's 52nd annual Air and Water Show.

Vaughn has been in Chicago this summer for the filming of The Dilemma, a new Ron Howard movie also starring Kevin James, Jennifer Connelly, Winona Ryder, Channing Tatum and Queen Latifah.

The actor did not seem afraid of Saturday's jump, probably because he was attached to the U.S. Army's Golden Knights--who have plenty of skydiving experience.
