This week, cannabis culture lost a notable film and TV director in Danny Leiner, 57, who passed away after a long battle with cancer.

Leiner is best known for helming smoke sesh staples 'Dude, Where’s My Car?' and 'Harold and Kumar Go To White Castle', as well as episodes of 'Arrested Development,' 'The Office,' and 'The Sopranos.' 

The success of these films led Leiner to become a key figure behind the 'stoner movie' resurgence of the late 90’s and early 00’s. Along the way, he helped jumpstart the film careers of several well-known actors like John Cho, Kal Penn, and Ashton Kutcher—all three of whom honored the late director on Twitter after hearing the news.

Leiner made his first feature film, 'Layin’ Low' - starring Jeremy Piven and Edie Falco in 1996 - and would go on to make four more in his lifetime.

Let's honor the man's oeuvre by revisiting what is arguably the greatest celebrity cameo of all time.
