Sydney Sweeney screams in terror as huge spider bites her on set of latest project

Sydney Sweeney opened up about an “absolutely terrifying” experience with a dangerous animal while filming Anyone But You in Australia.

The actress made a guest appearance on The Tonight Show Starring Jimmy Fallon where she lifted the lid on being bitten by a Huntsman spider.

Speaking on her experience down under, the star warned “Anything could kill you,” as she revealed: “ I had a spider that was in my vent the leg was sticking out.”

While Jimmy cringed and screamed: “No,” Sydney continued: “You have to shake your shoe before you put your shoe on.”

The host shared his own experience, adding: “That’s what they told me, when you wake up you have to shake your shoe or you’ll die from a poisonous spider.”

The notion of dangerous animals in Australia was also referenced in the upcoming movie as Sydney was forced to hold a Huntsman spider during a scene.

However, things took a scary turn as exclusive behind-the-scenes footage revealed she was bitten.

The 26-year-old explained: “We’re filming and the thing just starts biting me, but we’re in the middle of the scene and I’m supposed to be screaming.

“But then my screaming got a little serious … they thought I was making serious, dramatic choices in a rom-com.”

Sydney added: “No one cut, so I’m just standing there with a spider on my arm biting me and I’m screaming and everyone’s watching.

“Glen was the only one who was like ‘Whoa whoa whoa, I think this is a little real, we had to cut.”

Jimmy then shared the actual note written about the incident from the production set which joked that she was bitten by a spider, and is now "Spiderwoman."

Sweeney also remarked that they didn't even know about her upcoming Madame Web film, where she portrays Julia Carpenter, one of the women who has alternately held the superhero names Arachne, Madame Web, and Spider-Woman in Marvel comics.
