Milo Ventimiglia described the 'mischief' he got up to while filming 'Gilmore Girls,' including graffiti stencils of rats and carving his name around the studio

• Milo Ventimiglia used to spray-paint Banksy-style artwork around the studio lot, he said.
• The actor told Jennifer Hudson it was how he amused himself while filming "Gilmore Girls."

Milo Ventimiglia used to spray-paint Banksy-style artwork and carve his name at different places at the Warner Bros. Studios lot in Burbank, California, he said.

Speaking on "The Jennifer Hudson Show" on April 28, Ventimiglia said that he was often "causing mischief" during long "Gilmore Girls" filming days in his early 20s.

Ventimiglia said it felt nostalgic to be back at the same lot as "Gilmore Girls" used to film in. "I consider Warner Brothers the studio that raised me," he said.

He then told Hudson that his character on the show, Jess Mariano, was "always causing trouble," but added that he would also cause some mischief himself when he was working long days on the show, and occasionally got bored.

"I was really into stencil work, like Banksy and stuff like that, and so I cut this stencil based on a Banksy stencil of a little rat holding a megaphone with some audio phones and I proceeded to spray-paint it in different places around this lot here," he told Hudson.

"My plan was to do it on a massive level on these late nights when I'm filming here and then call the studio control and say, 'You have a rat problem.' But I never had the guts to do just that, so we left it a couple times near my parking spot and whatnot."

He also said that he "might" have carved his name in "a few studio locations too."

Ventimiglia played Jess on "Gilmore Girls" from 2001 to 2006 when its original run ended. He reprised the role — along with much of the original cast — for the show's four-episode Netflix reboot in 2016. He went on to appear in various TV shows and movies, including starring in "Heroes" from 2006 to 2010, and "This Is Us" from 2016 to 2022.
