Another of Columbia's myriad of Jack Holt actioners, Passport to Alcatraz casts the star as supposed enemy saboteur George Hollister. In truth, Hollister is on "our side", merely posing as a foreign spy to get the goods on a sabotage ring. The story reaches its peak in an explosives factory which the bad guys are using as their headquarters. Despite making several bonehead plays that no real undercover agent would be caught doing, Hollister manages to rout the villains and make the world safe for Democracy and future Jack Holt B-pictures. The film's barely relevant title was altered to Passport to Hell for its original New York showings. ~ Hal Erickson, Rovi
