Seth Rogen recently appeared on “Watch What Happens Live” and wrestled with the prospect of making a sequel to “The Pineapple Express,” his beloved 2008 stoner comedy that grossed more than $100 million at the worldwide box office.

Rogen and Franco, 47, made a number of comedies together in the 2000s and 2010s. They even famously included a miniature parody-style sequel to Pineapple Express in their 2013 disaster comedy This Is The End.
