Making it as a performer in Hollywood means making the big bucks, and it's always fascinating to see how much stars make for projects of all sizes. Some stars make millions on TV, others make seemingly nothing in classic hits, and some earn colossal paydays on the big screen. No matter the case, fans always want the details on celebrity paydays.

Julia Roberts is no stranger to making millions of dollars, and a few years back, the actress was able to score millions for a few days worth of work.

Let's take a look at Roberts and see which box office bomb paid her a fortune.

Julia Roberts Is A Legend

When it comes to the biggest actresses in modern history, there aren't many names that can stack up to Julia Roberts. Yes, there are plenty of success stories out there, but Roberts is a modern pioneer who paved the way for the mega salaries we see today.

The actress first gained notoriety in the 1980s with Mystic Pizza, but it would be 1990's Pretty Woman and Flatliners that launched her to superstardom. She wasn't making a lot back then, but as her fame increased, so did her paydays.

Throughout the '90s and 2000s, Roberts would land in one hit after another. This helped her cement her place as the Queen Bee of Hollywood, and while other actresses were doing some great things, they were all trying to keep pace with Julia Roberts.

Per The-Numbers, Roberts' movies have generated over $6 billion on box office revenue. Considering that she's never been involved with a massive franchise, save for her Ocean's films, we have to give credit where it's due. Few people can pull down numbers like this without the aid of billion-dollar franchises, but Roberts made it happen thanks to choosing outstanding projects with widespread appeal.

Though she has nothing left to accomplish, Roberts still seeks out fresh projects, which should simply add to her legacy.

With all the success that Roberts found on the big screen, it goes without saying that she's made a ton of money during her years in entertainment.

She Commands A Huge Salary

According to Celebrity Net Worth, Julia Roberts is currently sitting on a $250 million fortune, a lot of which came from starring in massive movies.

During her park years, she was earning $20 million per movie, which helped set a precedent for female performers. Her movie earnings, combined with other ventures, net her up to $30 million annually, per Celebrity Net Worth.

The site even touched on Roberts' lucrative endorsements, writing, "Roberts landed an endorsement deal with Gianfranco Ferre in 2006, for which she was paid $6 million. She is also the global brand ambassador of cosmetics brand Lancome Paris since 2009. She made a five-year deal with Lancome in 2010, which she earned $50 million for."

Recently, she made the transition to TV, and she was able to land a fortune for Gaslit.

Robert's salaries are huge, and one movie of hers paid her millions to be on set for just a few days.

'Mother's Day' Paid Her $3 Million For 4 Days Of Filming

So, which Julia Roberts movie paid her a fortune for limited filming time? Turns out, it was none other than Mother's Day, a box office disappointment that the majority of people have completely forgotten about.

According to Variety, "Julia Roberts earned $3 million for “Mother’s Day” for a supporting role that required her to shoot for only four days, Variety has learned. That means her rate — of $750,000 a day — still puts her among the top-earning actresses in Hollywood. But it’s nowhere near the record (for a woman) $20 million she received at the peak of her career for 2000’s “Erin Brockovich,” a legal story that grossed $250 million worldwide based on the sheer power of its star."

The film's ensemble cast featured Jennifer Aniston, Kate Hudson, Jason Sudeikis, Shay Mitchell, Timothy Olyphant, and more.

Mother's Day functioned as Garry Marshall's final film before his passing, and it was yet another film of his based around a holiday. Previously, Marshall crafted movies like Valentine's Day and New Year's Eve, which were successful in their own right.

Sadly, Mother's Day was a box office disappointment, failing to gross $50 million globally.
