Leiner, a longtime friend of 'Sopranos' star Edie Falco, helmed the New Jersey-set stoner comedy starring Montclair native Kal Penn and John Cho.
Director Danny Leiner, who helmed the New Jersey-set stoner comedy "Harold & Kumar Go to White Castle," has died.
Leiner, who was 57 when he died on Oct. 18, was also known for directing TV series including one episode of "The Sopranos" and the successful film comedy "Dude, Where's My Car?" in 2000.
Leiner's brother, Ken, told the Hollywood Reporter that the director died after a long illness, having been diagnosed with cancer.
"Harold & Kumar Go to White Castle" stars John Cho and Montclair native Kal Penn as friends living in Hoboken who embark upon an epic mission for White Castle after getting stoned and contracting a strong case of the munchies. Their fast food fantasy is seemingly thwarted at every turn. On their way to a White Castle in Cherry Hill, they find themselves in Newark, Princeton and the wilderness of South Jersey.
The film, written by Randolph's Jon Hurwitz and Hayden Schlossberg, spurred sequels in 2008 and 2011.
"Danny's sense of humor alone should get him into heaven, not to mention he was an all around cool dude," Schlossberg tweeted on Saturday.
"We lost a great man today," Hurwitz tweeted. "'Harold & Kumar Go To White Castle' was not only my first film, but also my first time on set. I was there every day, because Danny demanded it. Most writers don't get that treatment. And it fast tracked my path to directing. Thank you, old friend."
Penn, 41, a graduate of Freehold Township High School, remembered Leiner.
"Very sad to learn that our friend Danny Leiner passed away," he tweeted on Saturday. "We initially got to know each other when he directed Harold & Kumar Go To White Castle. Sending my love to his family & friends. He was such a funny, thoughtful, encouraging person."
Cho, 46, also memorialized Leiner.
"Danny was so sharp, so funny, and a great dinner companion," he tweeted. "To his friends and family, my deepest condolences."
Ashton Kutcher, 40, who starred alongside Seann William Scott in "Dude, Where's My Car?" also remembered Leiner.

"Rip Danny Leiner," he tweeted. "Thank you for putting up with that young actor who thought he knew way too much way too soon in his career. ....and theeeeen? No and then!"
Leiner directed the episode of "The Sopranos" titled "Luxury Lounge" in 2006, during which Christopher Moltisanti (Michael Imperioli) tries to sell Ben Kingsley on starring in his movie project with Carmine Lupertazzi Jr. (Ray Abruzzo). The episode featured Lauren Bacall.
Leiner also directed episodes of "The Tick," "Arrested Development," "Felicity," "Gilmore Girls," "Party of Five" and HBO's "The Mind of the Married Man."
The director, who grew up in Park Slope, Brooklyn, first met "Sopranos" star Edie Falco when they were both students at the State University of New York at Purchase. Leiner directed Falco and John Leguizamo in the short film "Time Expired" in 1992, and teamed up again with Falco for "Layin' Low" in 1996 and "The Great New Wonderful" in 2005, about life in post-Sept. 11 New York City.
