Enjoyably corrupt and thrill-drunk. John Travolta, looking like an older, sleazier Vincent Vega in ”Pulp Fiction,” plays a shadowy supersleuth who presides over a glibly crooked Mission: Implausible. Hugh Jackman, with his so-who’s-buying-the-next-round? terseness, is the subterranean hacker whom Travolta hires to break into the DEA’s computerized bank file. The director, Dominic Sena (”Gone in 60 Seconds”), is one of the new pulp kings who specialize in staging kicks that are so glossy and picturesque they’re nearly abstract. ”Swordfish” is trash, all right, but it’s canny and stylish and highly burnished trash.
