The Cannonball Run brings Burt Reynolds, Roger Moore, Farrah Fawcett,Dom DeLuise, Dean Martin, Sammy Davis, Jr. and an all-star cast to the staryting line of the ultimate auto race., a madcapcross country scramble that roars full-speed ahead. Hal Needham, the director of such souped-up hits as "Smokey and the Bandit," "Hooper" and "Smokey and the Bandit II" is at the helm of a wild action-comedy inspired by an acctual event: The Cannonball Sea-To-Shining-Sea Memorial Trophy Dash., an anything- goes, all-stops-out and thoroughly illegal- competition that has grown to legendary proportions in the last ten years.
