When it comes to knocking it out of the park at the box office, a few different factors need to come together seamlessly. But in many cases, one missing element can make a movie flop.

While it may take millions of dollars to film a movie and get it out into theaters, production companies don't always get their money back -- even when they hire Julia Roberts to headline their projects.

Do Julia Roberts Films Always Gross Millions?

The short answer is no, not every Julia Roberts film is a hit. In fact, she's had a few flops in her career, and not just on film. Some of her theater performances have been criticized, too.

To be fair, most of Julia's work has been critically acclaimed. 'Steel Magnolias' was iconic, 'Pretty Woman' was a gem (though it almost had a very different vibe altogether), 'Runaway Bride' charmed audiences everywhere, and countless other movies cemented Julia as a Hollywood hit.

But one of her earlier projects just didn't make much money, even though the talented Roberts was part of the cast.

Which Julia Roberts Film Made The Least Money?

When it comes to box office income, Julia Roberts has had some winners. In fact, 'Pretty Woman' was her highest-grossing ever at $463M, per IMDb. But in terms of her lowest-grossing ever? It's probably a film title few folks have ever heard of.

In fact, the movie 'Firehouse' never even made it to the box office. Clearly, a movie that's straight-to-VHS (hey, it was 1987) can't make a single dollar in theater ticket earnings. It's not all Julia's fault, though; the movie didn't even credit her, though her character had a name (Babs).

But despite her unforgiving foray into film, Julia Roberts went on to have plenty of success, even after that R-rated movie bombed. It wasn't profitable in the conventional way, but it did help get Julia's career off the ground in some way.

What Julia Roberts Film Tanked At The Box Office?

Alright, so the movie 'Firehouse' didn't make it to the box office at all. So while it was technically Julia's lowest-profit film ever, there's another one that went to the box office but didn't earn much.

IMdb confirms that the 2008 movie 'Fireflies in the Garden' only made $3 million at the box office, making it one of Julia's lowest-grossing films to ever hit the theaters.

The R-rated film even featured a super-talented and well-known cast, but that didn't help matters. Ryan Reynolds and Hayden Panettiere, at least, went down with Julia Roberts on the film, which also didn't earn rave reviews on IMDb or anywhere else.

Of course, Julia went on to star in a movie that paid her $20M, so her box office failures probably don't haunt her today.
