'Bridget Jones Baby' Madrid Photocall
Patrick Dempsey, Renee Zellweger and Colin Firth attend a photocall for 'Bridget Jones Baby' at Villamagna Hotel on September 9, 2016 in Madrid, Spain.

It’s been 12 years since the 2004 release of “Bridget Jones: The Edge of Reason,” but the Bridget Jones’s Diary franchise is back on Sept. 16, and its lovably quirky star is pregnant. Of course, things are always complicated in Jones’ world, and this time the catch is she’s not sure if her ex Mark Darcy or her new American love interest Jack Qwant is the father of her baby.

Here’s a look at the stars behind “Bridget Jones’s Baby” — and which one is making the most money.

Colin Firth is back to reprise his role of Mark Darcy, Bridget’s now ex, a kind — albeit a bit stuffy — upper class, human rights lawyer. “Bridget Jones’s Diary” author Helen Fielding killed Mark Darcy off in the franchise’s third book, “Mad About the Boy,” so fans will be relieved to hear the third film is based on her columns, not the novel.

In addition to the notoriety gained for his work on the Bridget Jones’s Diary series, Firth has been honored with dozens of awards for other projects. In 2011, he won honors for his role as King George VI in “The King’s Speech,” including an Oscar and Golden Globe.

In total, the actor’s films have grossed over $3.58 billion in theaters worldwide. His top five highest-earning movies include:

  • “Mamma Mia!” — $609.8 million
  • “Kingsman: The Secret Service” — $414.4 million
  • “The King’s Speech” — $410.9 million
  • “A Christmas Carol” (2009) — 325.3 million
  • “Shakespeare in Love” — $289.3 million

Not only is Emma Thompson starring in “Bridget Jones’s Baby,” she also helped write the screenplay. In the film, she plays Dr. Rawling, Bridget’s ob-gyn, who is thoroughly entertained by her patient’s paternity dilemma.

Thompson has received top honors for her work in front of and behind the camera. She won an Oscar and Golden Globe in 1993 for her lead role in “Howards End” and another Oscar and Golden Globe in 1996 for penning “Sense and Sensibility.”

The accomplished actress has dozens of credits to her name and, in total, her films have earned approximately $2.4 billion worldwide. Unsurprisingly, the Harry Potter franchise films top her list of her highest-grossing films worldwide:

  • “Harry Potter and the Deathly Hallows Part 2” — $1.3 billion
  • “Harry Potter and the Order of the Phoenix” — $939.9 million
  • “Harry Potter and the Prisoner of Azkaban” — $796.7 million
  • “MIB 3” — $624 million
  • “Brave” — $540.4 million

Renee Zellweger, the title character of the Bridget Jones’s Diary series, is back to reprise her role as the beloved heroine searching for her happy ending. At first, it seems like she’s picked up the pieces after her failed marriage to Mark Darcy, but of course, it’s never that easy for Bridget.

The actress has won numerous accolades. In 2005, her work on “Bridget Jones’s Diary” earned her a People’s Choice Award, and in 2004, she received an Oscar and Golden Globe for her portrayal of Ruby Thewes in “Cold Mountain.”

Since starting her acting career in the early 1990s, Zellweger has become an A-lister with several hits to her name, bringing in more than $2.5 billion at box offices worldwide. Her top-earning films include:

  • “Shark Tale” — $367.3 million
  • “Chicago” — $306.8 million
  • “Bee Movie” — $287.6 million
  • “Bridget Jones’s Diary” — $281.9 million
  • “Jerry Maguire” — $273.6 million

A movie in the Bridget Jones’s Diary series wouldn’t be complete without a love triangle, and Patrick Dempsey serves as the latest addition to Bridget’s love life, playing her handsome new American love interest Jack. Dempsey effectively replaces Hugh Grant as one of Jones’ suitors, who opted not to reprise his role as Daniel Cleaver, her former boss, ex and perpetual ladies man.

Dempsey’s most famous for his work as Dr. Derek Shepherd — aka McDreamy — on “Grey’s Anatomy.” He played the part from 2005 to 2015, and garnered $350,000 per episode, according to CelebrityNetWorth, which earned him the No. 9 spot on Forbes’ The World’s Highest-Paid TV Actors list for 2015. Dempsey won a number of awards for his work as McDreamy too, including a 2015 People’s Choice Award.

Some of Dempsey’s most notable box office hits have earned serious cash at theaters globally, including:

  • “Transformers: Dark of the Moon” — $1.1 billion
  • “Enchanted” — $340.5 million
  • “Valentine’s Day” — $216.5 million
  • “Sweet Home Alabama” — $180.6 million
  • “Made of Honor” — $105.9 million
