The cameras were still rolling when Sweeney, bravely holding a huntsman spider, got a taste of its bite. Her immediate reaction was nothing short of soul-stirring.
Watch the video:
From TMZ:
Normally, we'd call this a blooper -- an outtake from the set of her rom-com "Anyone But You," which was filmed in Australia -- but it's hard to laugh when you see, and hear, her scream.
Syd described it as a "soul scream" when she revealed the clip on Wednesday night on 'The Tonight Show.' She says she was supposed to act as if the trained Huntsman spider bit her, but then it truly had a feisty nibble on her hand.
As you can see, her eyes are wide open in panic ... and she shrieks at the top of her lungs while convincing others, including costar Glen Powell, that she's actually being bitten -- and not faking for the scene.
Huntsman spiders are rather rampant in Australia and, of course, they're famous for their bite. So it's pretty weird that Sydney would decided to pick one up and just casually hold it.
