In “Taurus”, director Tim Sutton teamed up with Baker for a film that blurs reality and fiction, casting Baker as Cole, in a study of superstardom and its pitfalls. The similarities between Baker and Cole are certainly no coincidence.

“We almost were shying away from it being autobiographical,” he told a news conference at the Berlin Film Festival yesterday. “It felt like… it just became me.”

Like Baker in his earlier career, Cole is successful but struggles with substance abuse. Maddie Hasson plays Ilana, the protagonist’s personal assistant, who tries to keep him on track while enduring his manic episodes.

But between skipped meetings, constant drunkenness and cocaine addiction, Cole’s life spirals out of control. And the film was the therapy he never had, Baker said.

“I got to have… onscreen therapy for things I never really dealt with,” said Baker, who previously worked with Sutton on the 2021 Western “The Last Son”.

Baker’s fiancee Megan Fox makes a brief appearance in the film, playing Cole’s ex-wife.

The film’s production title was “Good News”, but the new title was chosen to match Baker’s star sign.

“I’m hoping that people can watch it, and I’m the muse for someone to find their own inspiration and find a will to live,” he said.

Other highlights at the film festival, which runs until Sunday, included “Good Luck to You, Leo Grande”, which star British actress Emma Thompson as an inexperienced teacher getting a sex education from a young male escort; “The Passengers of the Night”, a tribute to the night-time radio of the early 1980s; and “Rabiye Kurnaz vs George W Bush”, about a German-Turkish mother’s quest to free her son from Guantanamo prison.
