Milo Ventimiglia revealed this month that he is officially reprising the role of Jess Mariano in Netflix's "Gilmore Girls" revival. The actor, who has since gone on to star in shows like "Heroes," opened up about his character during an appearance at Wizard World Comic Con, giving fans some idea of what to expect from the show's resident bad boy.

According to Us Weekly, Ventimiglia's character has been "up to Jess s---" since last we saw him in 2007. The actor says he will be a bit bitter when the show premieres on the streaming service. Despite Jess being "ornery," Ventimiglia, 38, says his presence around Stars Hallow — the small suburban town in which the series takes place — will serve as a catalyst for change among some of his co-stars.

"Jess is back. I had my first day of filming on Tuesday this week back at Warner Bros., which is a lot of fun. It's kind of the studio that raised me," Ventimiglia said. "And Jess is up to Jess s---. He's Jess. He's a little salty and ornery and kind of doing his own thing and has zero tolerance for anything — or anyone."

Ventimiglia is just one of many stars returning to "Gilmore Girls." As was previously reported, a majority of the original cast — including Alexis Bledel, Lauren Graham and Kelly Bishop, who played Rory, Loreli and Emily Gilmore, respectively — will be returning. They will be joined on set by Scott Patterson, who played Luke, as well as Jared Padalecki, Rory's first love Dean Forester, according to TVLine.

Melissa McCarthy, who played Sookie St. James on the original show, revealed via Twitter that she had not been asked to return to the series. As Entertainment Weekly reported, she wished her co-stars the best on Feb. 2, apologizing to a fan who had inquired. McCarthy's response shut down rumors that scheduling conflicts had kept her away from the reboot.
