Cinching in at her slender waist and taut midriff before flowing into an elegant skirt, the dazzling gown featured lines of glittering purple sequins which caught the light as the star posed.
Her brunette tresses were styled in big, bouncy waves, parted in the middle, while her sparkling features were enhanced with smoky shadow, long lashes and a fushcia lip.
Tomb Raider star Hannah, 28, who plays F'Nale Zandor in the sci-fi film, wowed in a vibrant canary yellow gown which featured crystal embellishment along the neckline.
Flaunting her ample bust and trim waist in the dress, it gracefully flowed into a chic ruched skirt.
Her brunette tresses were swept over to the side while her pretty features were accentuated with smoky shadow, fluttery lashes and a rose lipstick.
Adding an extra touch of sparkle, she slipped on some glittering crystal chandelier earrings.
Ready Player One is set in a future Dystopian earth, where humanity spends its time in an interconnected virtual space known as the OASIS, to escape the desolation of Earth's cities.
The founder dies and offers ownership of the space and $500bn to the first person who can find a hidden treasure within the space, by problem-solving and playing games, with a battle ensuing between a young man and his friends and a corrupt megacorporation.
The film, which also stars Simon Pegg, Mark Rylance, Ben Mendelsohn and Lena Waithe, will be released in the US on March 29.
It is based on the novel by Ernest Cline.
Although the premiere suffered technical difficulties when the theatre's sound system went down during a crucial scene - leading it to be replayed- it won acclaim from critics and fans alike.
