But all eyes turned to Harry and Chris when footage emerged that some fans claimed showed Harry spitting on his co-star as they sat down for the premiere screening.
Spread across Instagram, TikTok and Twitter, the clip quickly went viral and sparked massive debate and animosity between fans of the two stars.
Chris then had to clear the air, denying the bizarre rumours that Harry spit on him.
“This is a ridiculous story — a complete fabrication and the result of an odd online illusion that is clearly deceiving and allows for foolish speculation,” a spokesperson for the actor told People.
“Just to be clear, Harry Styles did not spit on Chris Pine. There is nothing but respect between these two men, and any suggestion otherwise is a blatant attempt to create drama that simply does not exist.”
Harry may not have spit on Chris, but footage from other press engagements on the day allegedly showed the veteran actor looking less than impressed with his co-star.
Fans claim that Chris looked frustrated and was “holding in screams” as pop icon Harry answered questions during joint interview appearances.
Photos from the press conference, where Chris was asked only one question, also seemed to catch the star looking bored.
These minor moments have given rise to fan theories that Chris was unimpressed at being cast alongside the singer, who has a very limited acting resume , though there’s no evidence to prove this.
Others have insisted these new claims are just more “drama” built off the alleged feud between two other big players in Don’t Worry Darling; Olivia Wilde and Florence Pugh.
The two women seemed to avoid each other during their Venice Film Festival appearances, with Florence skipping the press conference and keeping her distance from the director on the red carpet.
Rumours of tension between them have been swirling for months – you can read up on the supposed animosity here, though both parties have carefully dodged the rumours.
