Happiest Season star Kristen Stewart has joined the upcoming comedy feature Sacramento.

According to Deadline, the 33-year-old is set to star alongside Maya Erskine, Michael Cera, and Michael Angarano.

The film, which is labelled as a “road-trip” comedy, follows two best friends Rickey (Angarano) and Glenn (Cera),  as they navigate married life with their respective wives.

However, the two decide to shake up their mundane lives by taking a spontaneous and eye-opening road trip from Los Angeles to Sacramento.

Stewart has signed on to play Cera’s wife, Rosie, while Erskine is set to portray Angarano’s wife, Tallie.

In addition to his starring role, Angarano is set to direct the film and co-write the script alongside Chris Smith.

Lastly, the forthcoming project is set to start production this spring.

In a statement to the aforementioned news outlet, Angarano expressed his excitement over the film and its star-studded cast.

“We feel grateful and very excited to make a movie like Sacramento. Chris Smith and I started writing this film years ago, after a pilot of ours didn’t get picked up,” he explained.

“We’re honoured o be working with this wildly talented cast and crew led by Stephen at Bee-Hive who is not only a great partner, but a true collaborator. It’s already been quite a journey but we’re finally ready to go make a movie.”

Sacramento is just one of the many projects that Stewart has signed on to in recent months.

Back in February, it was reported that the Twilight star would be portraying bisexual writer, philosopher and political activist Susan Sontag in a biopic.

According to a report from Screen Daily, the author’s upcoming biopic will be based on Ben Moser’s biography, Sontag: Her Life and Work.

Unlike other biopics, the Brouhaha Entertainment produced project – which is tentatively titled Sontag – will reportedly follow a meta-like format and include documentary footage of Stewart attending the Berlin Film Festival.

“We’re using Berlin as a moment to kick off the project and do documentary footage of Kristen as the head of the jury and talking to her about how she’s going to become Sontag,” explained Brouhaha Entertainment co-founder Gabrielle Tana.

“It will be a drama, but with a documentary aspect to it. Kirsten has a wonderful approach to storytelling, and this is reflective of that, so she will use the documentary in it.”
