Films in the Marvel Cinematic Universe are, traditionally, kept tightly under wraps until they hit cinemas. From surprise cameos to plot twists, industry bosses try to keep a lid on any spoilers, with some stars revealing they even signed non-disclosure agreements preventing them from spilling details.
However, it appears one thing Marvel cannot keep a lid on is Russell Crowe.
The New Zealand-born actor has seemingly confirmed which character he'll be playing in the fourth chapter of the Thor franchise, and in the process revealing a whole new strand of the MCU.
Crowe, 57, told Australian radio show Breakfast with The Murphys on Thursday that he will be portraying Olympian god Zeus in Thor: Love and Thunder.
The film, which is currently shooting in Australia, is helmed by Thor: Ragnarok director Taika Waititi and will star action hero Chris Hemsworth, Tessa Thompson and Natalie Portman, reprising her role as Jane Foster.
Crowe told the radio show that he was about to embark on his last day filming, saying: "Now, I'm gonna get on my bicycle, I'm gonna ride up to Disney-Fox studios ... and round about 9.15, I shall be Zeus in Thor 4. It's my last day of Zeus-ing about."
If the actor's claims turn out to be true, it will mark the debut of the Greek god of sky and thunder in the cinematic franchise. The character appears in Marvel comics, but has not made it to the big screen thus far.
However, it's not known if he will make a brief cameo, perhaps even as a Zeus impersonator, or play a fully fledged god.
Marvel Studios has not yet confirmed or denied Crowe's character, though Deadline revealed in March that the actor was set to appear in the highly anticipated film.
Thor: Love and Thunder will also star Christian Bale, who is set to play the villainous Gorr the God Butcher, as well as Matt Damon and Guardians of the Galaxy's Chris Pratt and Karen Gillan.
The film is scheduled to be released on Friday, May 6, 2022.
