Scolari had cancer and had been ill for two years, his manager Ellen Lubin Sanitsky told CNN. He was 66.
Scolari appeared in numerous films and television series over the years, including “Newhart,” “Murphy Brown,” and “The Good Fight.” He won an Emmy in 2016 for his portrayal of Hannah’s father Tad Horvath on “Girls.”
“Bosom Buddies” was on the air for two seasons at ABC. On the show, Scolari and Hanks dressed as women in order to move into an affordable women-only residence. The two actors remained good friends in real life, with Scolari saying in an interview for Oprah Winfrey that Hanks toasted him at his wedding.
He also appeared in a TV adaptation of “Honey, I Shrunk the Kids,” “Gotham,” and played Peter Madoff in HBO’s “Madoff.”
On stage, Scolari starred in Broadway productions of “Hairspray,” “Sly Fox,” “Wicked,” “Magic/Bird” and “Lucky Guy,” alongside Hanks.
He is survived by his wife, Tracy Shayne, and children Nicholas, Joseph, Keaton, and Cali.
Colleagues and friends paid tribute to Scolari on Friday.
“Sad to see the news that Peter Scolari lost his battle with cancer,” Harvey Fierstein wrote. “There wasn’t a sweeter man on the planet. We performed together in HAIRSPRAY for a time and he was always a total delight. Farewell, dear Peter.”
Writer Robert King wrote, “Peter Scolari, who died today, was one of the funniest—sneakily funny—actors we’ve worked with. He always took a nothing scene and found different ways to twist it, and throw in odd pauses that made it jump. I will try to collect my thoughts more. He was just wonderful.”
