“Between Two Ferns,” for those out of the loop, is a popular series of “Funny or Die” videos, in which the comedian and actor Zach Galifianakis plays the preposterously stupid host of a public-access talk show. The result is an uproariously funny intersection of celebrity roasting, absurdist humor and typo-ridden chyrons — perfect fodder for five-minute YouTube consumption.

When “Between Two Ferns: The Movie,” the new Netflix adaptation, simply reproduces the material in question, it is laugh-out-loud funny. But it’s barely a movie.

In the wraparound material, which exists solely to get us from one segment to the next, Galifianakis is challenged by Will Ferrell — playing a juiced-up version of himself as the coke-addicted, click-obsessed head of Funny or Die — to create 10 new episodes in two weeks as he crosses the country. It’s that old standby, the road movie, with a promise that Galifianakis will get his own network show at the journey’s conclusion.
