'This Is 40' Trailer: Paul Rudd & Leslie Mann Are Every Couple In Judd Apatow's Newest (VIDEO)

Now that "The Great Gatsby" has moved out of the busy holiday season, you have more time to focus on any of the other seven major releases coming out during December. Like "This Is 40," Judd Apatow's comedy-drama about growing older with Paul Rudd and Leslie Mann reprising their characters from "Knocked Up."

The second full-length trailer for "This Is 40" debuted on Tuesday, and while it dispenses with the original's "We Are Young" music cue, the clip still looks fun(.), poignant and perfectly James L. Brooks-ian: That is Albert Brooks -- he of Brooks' classic "Broadcast News" among a dozen other classics -- as Rudd's onscreen father, providing the biggest laugh in the "This Is 40" trailer (and perhaps of the entire year). As per usual for Apatow, the cast of "This Is 40" is impeccable. Rudd, Mann and Brooks are joined by a cavalcade of famous faces, from Chris O'Dowd and Melissa McCarthy to Robert Smigel and Megan Fox, playing what seems like another take on her "Friends With Kids" character.

"It's about getting older," Mann, Apatow's real-life wife, said to the Los Angeles Times earlier this year. "What the hell happened? Am I making all the right choices? Is this where I'm supposed to be? Is this it? All of those dreams that you had when you were young, all of the possibilities, when you lock into marriage and kids, do the possibilities dwindle or go away?"

Find out when "This Is 40" arrives in theaters on Dec. 21.
