Jacob Elordi appeared to clash with a Venice Film Festival official at the world premiere of Frankenstein

Jacob told the official, before posing for photos with fans: "I'm going to take a picture right here."

After finishing, he turned back to the apparent staff member and added: "Don't ever tell me what to do."

Despite the tense moment, the fan who posted the footage described Jacob as friendly, saying he "was so nice" and "took photos with everyone he can."

They added: "He is so sexy and nice."

Jacob, known for his roles in Saltburn and Euphoria, was attending his first public event since splitting from Olivia Jade Giannulli, 25.

He wore a black suit with a bow tie and shoes to the screening at the Sala Grande Theater.

The screening of Guillermo del Toro's Frankenstein - a $120 million Netflix production - drew a 13-minute standing ovation, reported Variety.

People noted Jacob was "moved to tears" at the response as he hugged del Toro and co-star Mia Goth, 31, who plays Elizabeth Lavenza in the film, before bowing his head toward the audience.

During the ovation, Guillermo, 60, embraced Jacob.

Christoph Waltz, 68, also stars in the film, playing arms merchant Harlander in the adaptation, while Felix Kammerer, 29, portrays William Frankenstein.

The retelling of Mary Shelley's 1818 gothic horror follows the brilliant scientist Victor Frankenstein, played by Oscar Isaac, 46, as he creates a living creature that ultimately leads to tragedy.

Saturday's premiere also drew Aaron Taylor-Johnson, Jessica Williams, Jesse Williams and Sofia Carson.

On the red carpet, Jacob and Oscar stopped for selfies and autographs with fans. Inside the venue, an audience member shouted: "We love you, Jacob!" - to which the actor replied: "Love you too!"
