“THE ART of Richard Thompson,” the moving documentary short about the “Cul de Sac” creator’s professional and personal lives, has just been accepted as an “official selection” into the first Northern Virginia International Film Festival.

“We’re excited, and [are eager] to pack the theater for the screening,” Washington-based filmmaker Bob Burnett tells The Post’s Comic Riffs. (Exact screening dates in April are still to be determined.)

Burnett and writer Andy Hemmendinger, who head the video-production company GVI, released the film last November, after shooting interviews and gathering footage and images from Thompson’s quarter-century of a career. The Reuben Award-winning cartoonist ended his strip in 2012, as he battled Parkinson’s disease.

In making the film, “We did want to show the variety of artwork that he produced,” Hemmendinger told Comic Riffs last fall, “but we really looked for the images and moments that reveal Richard’s views of the world and his sense of humor.”

Upon the film’s release, Thompson said that the documentary “really humanized me.”

(The filmmakers first encountered “Cul de Sac” and “Richard’s Poor Almanac” in the pages of The Post, where both features launched.)

Last year, the Northern Virginia-based Thompson was also the subject of the “Art of Richard Thompson” retrospective book and a dual exhibit with Bill Watterson at the Billy Ireland Cartoon Library and Museum at the Ohio State University.

The film festival will be April 13-18 at the Angelika Film Center in Fairfax, Va.
