SAN FRANCISCO (CBS SF) — The 19th annual SF Sketchfest brings together another stellar line-up of talent to over 20 comedy and theater venues for 18 days of hilarious improvisation, live podcasts, tributes, stand-up and ensemble comedy over the course of nearly 300 shows.

Plenty of national names will be making appearances this year as the festival pays tribute to such television and film legends as Tony Shaloub, Sandra Bernhard, Kevin Nealon, Crispin Glover, original members of “The Monkees” Michael Nesmith and Micky Dolenz and the cast and creators from landmark children’s cartoon “SpongeBob SquarePants.” The schedule also includes the Bay Area premiere of Hamilton creator Lin-Manuel Miranda‘s new hit Broadway improvised hip-hop showcase Freestyle Love Supreme, stand-up talents Maria Bamford, Kristen Schaal, Patton Oswalt, Fred Armisen and George Wallace, noted improv troupes The Upright Citizens Brigade and The Groundlings as well as return appearances by noted locally grown talents like Doug Benson, Margaret Cho, Bobcat Goldthwait, beloved comedy groups Kasper Hauser and Killing My Lobster and popular drag queen Peaches Christ.

This year the festival spotlights television shows and landmark films with world premiere screenings (the new Netflix comedy “Medical Police” and It Started As a Joke, a documentary on the decade-long run of the Eugene Mirman Comedy Festival), animated programs like “Futurama” and “We Bare Bears” and tributes such cinematic creations as writer/director Whit Stillman‘s films Metropolitan and Barcelona, the Disney favorite The Journey Of Natty Gann, the over-the-top horror comedy Re-Animator and the disaster parody classic Airplane! The number of venues utilized by the festival continues to grow with spots in Oakland (the Fox Theater), the Mission District (Brava Theater Center and Brava Cabaret, the Chapel, the Alamo Drafthouse), North Beach (Speakeasy, Cobb’s Comedy Club), the Castro (Cafe du Nord, Swedish American Hall, the Castro Theatre), downtown SF (Pianofight, Punchline Comedy Club) and Hayes Valley (The Sydney Goldstein Theater, formerly the Nourse) hosting events.

On Friday, another full weekend of programming commences at the Castro when the SF Sketchfest pays tribute to iconoclastic actor and filmmaker Crispin Hellion Glover. Though best known for his breakout ’80s roles as nebbish teen George McFly in Back to the Future and speed freak Layne in the high-school murder melodrama The River’ Edge, Glover has maintained a unique career through the decades. While he regularly acts in mainstream films (What’s Eating Gilbert Grape? in 1993, later the Charlie’s Angels reboot and Hot Tub Time Machine), he also has made a name for himself as an explorer of the fringes with his live readings and slideshow presentations and surrealist films. The Castro hosts an evening with Glover featuring a Q&A session, his “Big Slide Show part 1” and a 15th anniversary screening of his 2005 avant-garde movie What Is It? (1/17, 7 p.m.).

Friday also brings a return visit from the popular Sketchfest attraction with a twist. Held at the Palace Theater and presented in partnership with Boxcar Theatre, old-time radio show style podcast The Thrilling Adventure Hour will be recast as an immersive show. Written and created by Ben Acker and Ben Blacker, the show features a performance in the Mainstage Cabaret before attendees can delve into a “choose-your-own-adventure” style experience throughout the venue. Participants include “MythBusters” host Adam Savage, noted comics Paul F. Tompkins and John Hodgman, actors Arden Myrin, Busy Philipps, Paget Brewster, John Ross Bowie, Craig Cackowski, Mark Gagliardi, Marc Evan Jackson, Hal Lublin, Annie Savage, Autumn Reeser and Janet Varney, musicians Jonathan Dinerstein, Jonathan Coulton, Jean Grae and Old 97s frontman Rhett Miller and more. engaging in impromptu encounters with audience members (1/17-18, 7 p.m.).
