It is the most famous red carpet in the world, with Hollywood stars preparing for hours to have their glamorous pictures beamed across the world.
So spare a thought for actress America Ferrera, who was left looking shaken after being targeted by a prankster who launched himself towards her and put his head up her skirt.
Ferrera, the Ugly Betty actress who stars in How to Train Your a Dragon 2, had been posing for photographs with colleagues Cate Blanchett and Kit Harrington when the stranger dived onto the red carpet and lifted up her dress.
The interloper, later identified as notorious Ukrainian prankster Vitalii Sediuk, attempted to put his head inside her voluminous white dress in front of the world’s press.
He was removed by security as Ferrera looked on in confusion. Her co-star Blanchett, the double Oscar winner, glared at Sediuk as he was taken away, as Game of Thrones actor Harrington took Ferrera’s arm to reassure her.
After taking a moment to compose themselves, the cast continued with the premiere of How to Train Your Dragon 2 without further mishap.
Ferrera, who rose to fame in as the lead role in the successful US television series Ugly Betty, appeared to shrug the incident off by the time the after party came around, and was seen relaxed and laughing with guests.
It is not the first time Sediuk has targeted a red carpet event.
In 2012, he attempted to repeatedly kiss Will Smith on the lips at the premier of Men in Black 3, earning himself a gentle slap in the face.
He has also been photographed awkwardly hugging actors Bradley Cooper and Leonardo DiCaprio, crouching to waist height to leave them uncomfortable.Perhaps we just don't need Beachcomber any more.
