Like many Seth Rogen films before it, “The Night Before,” a new R-rated Christmas movie that also stars Joseph Gordon-Levitt and Anthony Mackie, is packed full of cameos — gifts for discerning comedy nerds.

Rogen, Gordon-Levitt and Mackie are great as a trio of childhood friends who have spent the past 14 Christmas Eves together getting drunk, doing karaoke and eating Chinese food in New York City. The tradition began when Ethan (Gordon-Levitt) lost both his parents in a car accident in 2001. Now approaching their mid-30s, Isaac (Rogen) is expecting his first child, Chris (Mackie) is a star football player and Ethan is a flailing musician who can’t get over his ex (Lizzy Caplan).

The film plays out over the course of what is to be their final Christmas Eve together, and as “The Night Before” unfolds, funny people pop in and out of the story (most of whom I won’t spoil).

The writers of the film, which include director Jonathan Levine (“50/50”) and longtime Rogen collaborator Evan Goldberg, have a clear reverence for the supporting cast. Recognizable actors appear for a scene or two and act just as you would expect them to.

For example, “Broad City’s” Ilana Glazer literally steals every scene she’s in as the film’s self-described Grinch. Her character is so on brand that it almost feels like Glazer wandered off the set of “Broad City” and into this movie.

Another Comedy Central star, “Nathan For You’s” Nathan Fielder, plays the trio’s driver for the night, and he is, perhaps, even more awkward and odd than he is on his show.

Mindy Kaling, meanwhile, has some memorable exchanges with Rogen that lead to the film’s biggest cameo — and for the most part, Kaling is the same character we’ve come to know from “The Office” and “The Mindy Project.”

You could call this typecasting, but all the familiar funny faces give “The Night Before” an extra dose of holiday cheer.
