The Australian website Spotlight Reports tells us that the world premiere for the Kenneth Branagh directed Thor movie will be held in Sydney, Australia on Sunday April 17th, 2011.
Chris Hemsworth, who plays Thor, is from Melbourne, Australia – and the premiere will begin a two day promotional tour that will cover his hometown and also Sydney.
Spotlight Reports informs us that, “Walking the red carpet will be the film’s director Kenneth Branagh and Australian Chris Hemsworth in the title role of Thor, ‘The God of Thunder’ as well as Kat Dennings who stars as Darcy, Tom Hiddleston in the role of Thor’s brother Loki and Jaimie Alexander who plays Sif.”
Natalie Portman is noticeably absent from that list as she may be sitting this one out due to pregnancy. Anthony Hopkins is not mentioned, as well, – I think we can forgive the legendary actor if he can’t attend this one. Possibly, Hopkins could be working on another film or just hasn’t confirmed if he is attending or not.
Thor then opens in Australia on April 21st – a full two weeks prior to the US debut of May 6th. (Source)
