How much money would you want to wear a bad wig and hang out with Jennifer Aniston for four days?

If your answer is anywhere in the ball park of $US3 million, you’d better get Julia Roberts’ agent on your side.

The Oscar winner just scored that exact sum for her latest role as a home shopping network star in ensemble comedy Mother’s Day.

According to Variety, Roberts’ total time on set amounted to just four days, meaning she earned a whopping $US750,000 per day.

Amazingly, this isn’t even Roberts’ highest-paying gig – she scored $US20 million for her Oscar-winning turn in 2000’s Erin Brokovich.

So, was Roberts’ performance in Mother’s Day worth $3 million? In short, no.

The film, directed by Garry Marshall of Pretty Woman fame and also starring Aniston, Kate Hudson and Jason Sudeikis, grossed an abysmal $US8 million in the US over its opening weekend and just over $US10 million globally.

In comparison, animated children’s film The Jungle Book grossed $US103 million in the US on its opening weekend.

This lacklustre box office performance could have something to do with the film’s reviews, which have been critical at best.

“Director Garry Marshall is a menace,” Rolling Stone‘s reviewer declared. “He keeps killing holidays with all-star comedies in which a laugh would die of loneliness.”

The Hollywood Reporter joked: “A movie not even a mother could love.”

The rest of the attention the film has received has been focused on Roberts’ bizarre wig – a bright orange bob – which she also wore for her 1999 hit film Notting Hill.

This isn’t the first time in recent years a movie helmed by Roberts has flopped.

The Secret in Their Eyes pulled an unremarkable $32 million globally in 2015 while her 2012 Snow White film Mirror Mirror got lost among countless other adaptations.

For Roberts, this might mean she’s no longer as bankable a star as she was in the 1980s and ’90s – no real concern for a woman whose reported net worth is $170 million.

Actually, make that $173 million.
