Kevin Smith wrote, directed, and stars in which 2019 comedy film where titular stoner duo Jay and Silent Bob journey to Hollywood to stop a film studio from rebooting the "Bluntman and Chronic" movie?

The 2019 comedy film described is indeed "Jay and Silent Bob Reboot." Written, directed by, and starring Kevin Smith, the movie sees the titular stoner duo, Jay (Jason Mewes) and Silent Bob (Kevin Smith), embark on a cross-country journey to Hollywood. Their mission is to stop a film studio, Saban Films, from rebooting "Bluntman and Chronic," a superhero film based on their comic book alter-egos. This premise directly mirrors the plot of their earlier film, "Jay and Silent Bob Strike Back," making "Reboot" a meta-sequel that playfully rehashes familiar territory.

Jay and Silent Bob are iconic characters within Kevin Smith's "View Askewniverse," a shared fictional universe encompassing most of his films, comics, and television shows. They first appeared in Smith's debut film, "Clerks" (1994), as two drug dealers who spend their time loitering outside a convenience store in Leonardo, New Jersey. Over the years, the duo, with Jay's vulgar exuberance and Silent Bob's mostly taciturn wisdom, have become beloved antiheroes, appearing in every live-action View Askewniverse film.

"Jay and Silent Bob Reboot" not only revisits the familiar journey to Hollywood but also serves as a poignant, self-aware reflection on Smith's career and the characters' legacy. The film features numerous cameos from past View Askewniverse collaborators and other celebrities, adding to its nostalgic and celebratory feel. Beyond the comedic quest to reclaim their likeness rights, the narrative also delves into more personal themes, particularly Jay's discovery of a long-lost daughter, adding an emotional depth to the stoner comedy.
