Wolf (1994)

Seven-time Academy Award winning director Mike Nichols and three-time Academy Award winning actor Jack Nicholson and one-time Academy Award winning actor Christopher Plummer and three-time Academy Award nominee Michelle Pfeiffer and Niles from Frasier and James Spader team up for the most awarded and star-studded werewolf film of them all.

Jack crashes into a wolf while driving in the snow, and it bites his hand when he tries to move it out of the road. His doctor doesn't believe him, because there are no wolves in Vermont. He finds that horses don't like him anymore.

Jack is the gruff but well-loved lead editor of a large New York publishing house, which was just purchased by a rich businessman, Plummer, who plans on stirring things up. Jack and his team expect to lose their jobs in the coming days, and they're all supporting each other.

Jack's younger protégé, James Spader, pretends to be on his side while actually backstabbing him most thoroughly: taking his job and sleeping with his wife.

Plummer's daughter, Pfeiffer, is slightly kind to Jack, so they start a romantic relationship.

Jack starts getting super-senses: he can hear and smell everything in the building. This is how he catches his wife's affair with Spader.

He starts wolfing out and hunting at night, which he experiences as black outs and waking up in odd locations with blood stains. It takes him a while to work out that he's a werewolf, assisted by a crazy Indian professor who gives him an anti-werewolf talisman. Wolfing out involves putting on fake teeth and mussing his hair.

He defeats Spader in office politics and gets his job back, but Spader becomes very spiteful. Also, he's becoming a werewolf too, because Jack weirdly bit him.

Jack tells Pfeiffer he's a werewolf, which she doesn't believe at first, but all of the clues start to add up. She tries to help him with his growing troubles, because they've been dating for 8 hours so they're madly in love.

Increasingly creepy Spader starts hunting her, and murders much of her staff.

He tries to kill her, but Jack breaks out of his cage just in time for a werewolf battle. The defeat Spader and everyone lives happily ever after.

It's shot and scored in a maximally mid-budget 90s way, and the romance is based on two people behaving entirely irrationally. It mostly hinges on the enjoyment of watching Jack Nicholson and James Spader make interesting faces for two hours. They're so good at making interesting faces, though, so this works.
