"Chariots of Fur" (1995) was the final theatrical roadrunner cartoon directed by Charles M. Jones. There have been a couple other roadrunner cartoons aimed for the theatre, "Little Go-Beep"(2000) & "Wizzard of Ow"(2003).
Little Go Beep wasn't seen by many, it only had a special screening at a film festival.
Whizzard of Ow was shown on screens in Wal-Marts in the U.S. to promote Looney Tunes: Back in Action and was released as a special feature on the DVD.
Now for the feature presentation,
