Wolf (1994)

Aging publisher Will Randall is at the end of his rope when a younger co-worker snatches his job out from under his nose. But after being bitten by a wolf, Will suddenly finds himself full of youthful vigor. As he struggles to regain his position, he becomes enthralled with Laura Alden, his former boss’s daughter. And, as increasingly animal-like urges begin to overwhelm him, Randall worries that he may be turning into the creature that bit him.
