Really hate to pull the plug on this one; thought for sure somebody would get them, but it's been six days...
Red Mustang: The Deadly Tower (1975) - Lead actor: Kurt Russell - Actor in two Bond films: Clifton James
White Mustang: Targets (1968) - Lead actor: Tim O'Kelly - Director/co-star: Peter Bogdanovich - Famous actor co-star: Boris Karloff
Subject: Charles Whitman sniper incident in Austin, Texas (Targets borrowed many elements from this event plus a 1965 sniper incident in southern California where a 16-year-old boy shot at cars on Highway 101. It's a truly scary film - the sniper's last words are especially chilling. The Deadly Tower is very good, as well, and fairly accurate, but it's loaded with 1970s cars when it's supposed to be set in 1966.)
