A man rushed on to the red carpet at the Cannes Film Festival and crawled beneath the dress of actress America Ferrera.
Security officials quickly pulled the man away as he tried to hide under America's voluminous gown before the premiere of How To Train Your Dragon 2.
It was a bizarre incident on a red carpet renowned for its strict decorum.
The man was later identified as Vitalii Sediuk, a Ukrainian prankster known for such stunts.
Yet America did not seem ruffled on the carpet and was in good spirits at the movie's after-party, laughing with guests and taking pictures, although s he declined to comment on the incident.
The former Ugly Betty star was on her way into the Palais des Festivals for the world premiere of the DreamWorks animated sequel.
