Robert Pattinson just got a new (fictional) boss ... and it's Jay Baruchel.

Baruchel ("How to Train Your Dragon," "Knocked Up," "Undeclared") has joined the cast of "Cosmopolis," David Cronenberg's upcoming big-screen adaptation of Don DeLillo's 2003 novel, according to Deadline New York. The novel is a modern reinterpretation of James Joyce's "Ulysses."

In the film, Pattinson will play Eric Packer, a "financial wunderkind" in New York at the beginning of the 2000 dot-com bubble burst, who one day takes a major risk that could put his life in jeopardy. Baruchel, who is known for playing more reserved types, will take on the role of the company's shy founder who also acts as Packer's conscience in the film.

The actor, who turns 29 on April 9, can add "Cosmopolis" to his growing list of projects, which includes the sequel to "How to Train Your Dragon" and the hockey comedy "Goon".

Baruchel's casting adds to the already-diverse ensemble for Cronenberg's "Cosmpolis," which Pattinson heralded as a "great cast" that includes Oscar-winner Juliette Binoche, Samantha Morton, Paul Giamatti (who joked to MTV that he would "get to stalk" the "Twilight" star on set) and relative unknown Sarah Gadon, who will play Packer's estranged wife.

During a chat with MTV, Pattinson, who previously revealed that he immediately said yes to Cronenberg's offer to appear in the film, said of his co-star Gabon, "I've seen a couple of things she's done. She's really good. She has a great face."

Pattinson said he's currently preparing for "Cosmopolis" by "working with a dialect coach ... there's this very specific accent."
