The 5 familiar faces we all forgot were in My Best Friend's Wedding.

There are so many reasons why My Best Friend’s Wedding is remembered as one of the great Rom-Coms of its epoch, 22 years on; not least for its soundtrack cover of “I Say a Little Prayer (For You)” and its not-so-happy ending.

In the movie Jules learns that her ex Michael is engaged to be married to loveable Kimmy, forcing her to realise she’s in love with him. In sheer desperation, she flies to Chicago seemingly to attend the wedding, only to spend most of her time trying to sabotage Michael and Kimmy’s relationship.

And proving its place as one of everyone’s favourite 90s films, the actors who played the four main characters – Julia Roberts (Julianne Potter), Dermot Mulroney (Michael O’Neal), Cameron Diaz (Kimmy Wallace) and Rupert Everett (George Downes) – have reunited for the latest cover of Entertainment Weekly.

“You are cordially invited to attend the reunion of #MyBestFriendsWedding,” the magazine wrote alongside their cover.

But there are some important people who have slipped our minds, who also appeared in the 1997 film, which reportedly earned $300 million at the box office.

And before we reminisce about the five actors we forget featured in the classic film, here’s a look at Julia Roberts and Cameron Diaz, then and now…
