Unlike the 2018 event which occurred over three days, this time around, Comic Con will span four days from 21 to 24 September at Gallagher Convention Centre in Midrand.
Comic Con Africa tweeted on Friday: "Unfortunately due to a production delay in Budapest Anthony Mackie will no longer be attending Comic Con Africa."
"All pre-purchased photo ops and autograph sessions will be refunded shortly," was added.
Along with the tweet, Comic Con Africa shared a video of Anthony Mackie, while on set in Budapest, apologising for not being able to attend.
"Things have gotten a little out of hand here on set, so I'm stuck in Budapest," he explains.
He added: "I wish I was there. Hope you guys have a great time. Have a lot of fun. Take a lot of pictures. Enjoy yourself."
