Cape Town - Marvel's Falcon actor, Anthony Mackie, will no longer be attending Comic Con Africa 2019.
The news comes one week after Game of Thrones star Isaac Hempstead Wright (Bran) cancelled his appearance at the comic book convention.
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.
This is the second year in a row that Anthony has cancelled his appearance at Comic Con Africa.
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."
Other international stars on the line-up include iconic Star Trek actor William Shatner, The Vampire Diaries' Daniel Gillies, voice actors Nolan North and Troy Baker.
