Editor’s note: Cineverse / Scream seems to have pulled a Mummy on this one and posted a trailer with a broken audio track.

Editor’s supplementary note (Apr 23 2025): The original trailer ( https://www.youtube.com/watch?v=CRfdC8Hamvg ) was taken offline and a new version was posted with corrected audio ( https://www.youtube.com/watch?v=tBLbb8WMG7U ). I’ve updated this post to point to the corrected version of the trailer.
