You're telling me THAT moment in Pretty Woman wasn't planned? The magical movie moments that happened by accident...

One of the most memorable scenes in ‘Pretty Woman’ sees Richard Gere’s character Edward Lewis offer Julia Roberts' alter ego Vivian Ward a necklace. After he snaps the box shut when she tries to touch it she ends up laughing. This exchange was not planned, but Julia’s reaction was so unique that director Garry Marshall decided to use the scene in the final cut. He said: "She laughed so honestly that we left it in the picture."

Did you know that lead actress Anya Taylor-Joy was the mastermind behind the iconic scene where her character Beth makes a toast to her mother Alma’s death while on the plane? The hit Netflix series' creator Scott Frank confirmed this during a conversation with Jodie Foster for 92nd Street Y in 2020.

According to VH1, ‘The Notebook’ director Nick Cassavetes revealed that Ryan Gosling improvised one of the film's most famous lines. The line “What do you want?” followed by a more energetic repetition of “WHAT DO YOU WANT?”, was the actor’s idea. "It became one of the most iconic things from the film [that] wasn’t in the script. He just knew it... I like words, but I also like improvisation. He was so on it. We just let him go”, said Cassavetes.

The iconic kiss between Steve Carell's character Michael Scott and Oscar Nunez's character Oscar Martinez in 'The Office' was 100 percent natural. In a 2008 interview, Nunez revealed that they “were just supposed to hug but he came in really close, and I’m like, ‘Where is he going with this?’” The director decided to keep the peck in and the rest is history.

When Draco catches his henchman Goyle, who is really Harry having taken Polyjuice Potion, wearing glasses and reading he quips: "I didn't know you could read." This line was improvised by Tom Felton who played Draco. During a Q&A session on a Facebook Live session in 2011, Felton revealed to his fans that the line, which is one of his favourites, was added last-minute by director Chris Columbus.

KJ Apa’s ice punch as Archie Andrews in 'Riverdale' was a little more forceful that expected. During an interview with TVLine in 2017, the actor revealed that he got a little too into character. KJ said: "I wasn’t really punching the ice, I just got a little bit too excited, and I was punching a foam mat… sitting on the ice, but I was just kind of going for it. The actor broke his hand doing this!

In ‘Dirty Dancing’ there is a scene which shows Baby and Johnny crawl towards each other on the floor while ‘Love is Strange’ by Mickey & Sylvia is playing. According to Vogue, Patrick Swayze and Jennifer Grey were actually only rehearsing and warming up before shooting the scene, but director Emile Ardolino loved it so much that he decided to keep it in.

Quentin Tarantino’s western film had a scripted scene where Leonardo DiCaprio was supposed to slam his hand on a table as his unscrupulous character Monsieur. The actor ran through the scene several times in order to achieve the perfect scene, which only happened when he accidentally slammed his hand into glass and cut it. Leo and the crew kept filming and the blood made the scene more credible. The film’s producer, Stacey Sher, told Variety in 2012: “He never broke character. He kept going. He was in such a zone. It was very intense. He required stitches."

The extreme pain Viggo Mortensen's character Aragorn experiences after hitting his helmet was real and unplanned. The actor actually broke two of his toes while shooting the iconic scene but kept filming. On the DVD behind-the-scenes interview, director Peter Jackson said: "Viggo was actually feeling that pain, he actually turned that into performance. I mean he stayed in the character of Aragorn. He was letting that pain feed and drive his performance, which is pretty amazing."

The famous scene where Edward Norton's character punches Brad Pitt's character in the ear was also not in the original script. During an appearance on 'The Tonight Show Starring Jimmy Fallon' in 2019, Norton revealed that it was an accident, but director David Fincher decided the shot should stay in as both the hit, and the reaction, were very realistic looking.
