Roy Scheider makes a brave and largely successful leap out of his usual romantic lead roles to step into Gideon's dancing pumps, and supplies a plausible sketch of an extravagant, self-destructive, self-loathing creative dynamo, while Jessica Lange serves as a largely allegorical Muse, one of the various women that the philandering Gideon pursues (and usually abandons). Gideon's other romantic partners include Fosse's own protégé (and a major keeper of his choreographic style since his death), Ann Reinking, whose leggy grace is seductive both "onstage" and off.

Fosse/Gideon's collision course with mortality, as well as his priapic obsession with the opposite sex, may offer clues into the libidinal core of the choreographer's dynamic, sexualized style of dance, but musical aficionados will be forgiven for fast-forwarding to cut out the self-analysis and focus on the music, period. At its best--as in the knockout opening, scored to George Benson's strutting version of "On Broadway," which fuses music, dance, and dazzling camera work into a paean to Fosse's hoofer nation--All That Jazz offers a sequence of classic Fosse numbers, hard-edged, caustic, and joyously physical. --Sam Sutherland
