Lovable klutz Bridget Jones (Renée Zellweger) is back.

In "Bridget Jones's Baby", the British heroine is knocked up -- and she doesn't know if the father is long-time flame Mark Darcy (Colin Firth) or recent hook-up/internet dating millionaire Jack (Patrick Dempsey). What's a girl to do?

Here's what you need to know about the third film in the franchise, which opens on September 16.1. Hugh Grant Is AWOL
As his glaring absence from posters and ad campaigns might suggest, Grant's roguish Daniel Cleaver character does not make an appearance. (Exactly why he's missing is revealed early on in the film, but we won't spoil that here.)

2. It's Really Funny
Forget the meh 2004 second film ("Bridget Jones: The Edge of Reason"). This movie -- co-written by "Bridget Jones" author Helen Fielding, Emma Thompson (who costars as Bridget's doctor). and Dan Mazer ("Borat"), delivers more genuine laughs than just about any comedy so far this year. The film centers on Bridget as she struggles with a bitchy millennial boss, pregnancy, and her two potential baby daddies.

3. Paul Feig Almost Directed the Movie
The "Bridesmaids" director was originally signed, but left due to the usual "creative differences." Sharon Maguire, who directed 2001's "Bridget Jones's Diary," returned to take the helm for the third film.

4. You Don't Need to Read the Book
Why? Because the movie is not based on it.

In the third Bridget Jones book, "Mad About the Boy," published in 2013, Mark Darcy was (gasp!) killed off, leaving the now 51-year-old Bridget a widow with two children, a Twitter obsession, and a new younger man. Instead, it's based on the columns Fielding wrote for The Independent in 2005 about being a 40-something woman trying to become a mother before it's too late.

5. Bridget Jones May Return
When we talked to Zellweger, she said she's definitely up for more Bridget Jones, likely involving her misadventures as a mother. That sound you hear is us buying our advance tix now.
