A fun look at Cheech & Chong

   Movies rarely score a double triumph, connecting with their audience and with the national mood at the precise moment of their release. 

  That's my recollection of Up in Smoke (1978), the landmark Cheech & Chong comedy that focused on two pot-smoking guys who were too stoned to care about much of anything. They were also funny enough to create a near celebratory feeling among their fans, many of whom were as stoned as the protagonists of Up in Smoke, a road movie that became a kind of countercultural highlight reel.

  Up in Smoke was followed by eight other Cheech & Chong movies, the last an animated feature released in 2013. Although the Cheech & Chong filmography is decidedly mixed, the duo remained synonymous with pot-driven mirth.

   Now comes Cheech & Chong's Last Movie, a look at the individual and dual careers of Richard "Cheech" Marin and Tommy Chong. Marin, now 78, has appeared in other movies; Chong, 86, has done solo work. He also became a cannabis activist, and, in 2003, served nine months in a federal prison for selling drug paraphernalia over the internet.

   Billed as a documentary, Last Movie revolves around a car trip through the desert taken by Marin and Chong, who recall their lives and comedy exploits. Some of the scenes feel staged or, at least, prearranged, but the two still have chemistry, and the movie -- rich with clips and period footage -- serves up a tasty hunk of nostalgia.

   Marin and Chong were an odd couple. Marin, a Mexican-American, grew up in South Central LA. He wanted to be a potter. Half-Chinese and raised in Canada, Chong enjoyed early success as a musician.

   Before the movies, Cheech & Chong made a hit comedy album under the tutelage of music producer Lou Adler, who produced and received a co-directing credit for Up in Smoke. The movie grossed $104 million worldwide, but Cheech or Chong had signed a famously bad deal that favored Adler and others.

    Adler, by the way, appears in the film, and Cheech & Chong acknowledge the important role he played in helping them transition from improvisational club appearances to a national phenomenon.

    Eventually, Cheech & Chong lost some of that loving feeling for each other, arguing about who would direct their movies and who was responsible for writing them. They never officially broke up, but they had issues.

    Whether director Dave Bushell has made a "pure" documentary or not, Last Movie proves entertaining and informative. It also reveals the evolving personalities of comics who made the kind of pop cultural splash few have been able to match.
