According to a report from Pwinsider, WWE filmed some content with magician and illusionist Criss Angel while they were in Las Vegas, NV for SummerSlam. Angel has previously appeared for WWE as a “Guest Host” on Monday Night RAW and also performed one of his shows at the old “WWE New York” restaurant in Times Square.
For what it’s worth, Alexa Bliss received almost no reaction for her live entrance at SummerSlam. Damian Priest and Sheamus also didn’t get big reactions for their entrances.
As noted earlier here on eWn, the contactless payment system in Allegiant Stadium crashed during SummerSlam. This led to some of the vendors giving away free food/drinks to fans who were waiting in line and had already ordered their grub.
