“Speed Kills” (** out of four) was a perfectly watchable but unexceptional underworld crime melodrama about a speedboat racing champion and multimillionaire (John Travolta) who leads a double life involving the mob (including James Remar as Meyer Lansky and Tom Sizemore as a mob enforcer) and various illegal affairs that eventually end his marriage to his wife (Jennifer Esposito) and seal his demise. Travolta tries hard but is simply too old to convincingly play more-or-less the same role that Johnny Depp did in “Blow” years ago which this film emulates. Fast-paced and reasonably well-made but appears to be following a much-too-familiar pattern and predictability. It’s routine B-movies like these that “killed” Travolta’s career a second time.
