The highly anticipated movie stars Paul Mescal, Rossy de Palma and Elsa Pataky,- who is the wife of Chris Hemsworth.

He is currently filming the new movie alongside Natalie, reprising his role as the lead character.

Natalie’s character, Jane Foster, was absent for 2017’s Thor: Ragnarok, but was a key player in the first two Thor films, which were released in 2011 and 2013.

Jane will assume the powers of hammer-wielding Norse god Thor in the fourth movie in the Marvel franchise.

Director Taika Waititi has said the film will be based on Jason Aaron’s comic books, which are about Jane taking on Thor’s duties in his absence.

She will face off against Gorr the God Butcher in the new movie.

The upcoming blockbuster is being filmed in Australia after receiving a $24.1million location incentive grant from the Federal Government.

Thor: Love and Thunder is due for cinematic release in May 2022.
