She provided the Portuguese dubbing for Gwen Stacy in Spider-Man: Into the Spider-Verse and was cast in the comedy drama Parque Mayer in the same year.

She had her international breakthrough as Cleo Cazo in the DCEU film The Suicide Squad (2021), which earned her a nomination for Best Newcomer at the Portuguese Golden Globes.

[2] Melchior started her career in 2014 with several Portuguese film and television productions, including Ouro Verde, A Herdeira, The Black Book, and Parque Mayer.

Melchior was encouraged to present herself in a traditionally glamorous manner for her initial pre-audition meeting, but this approach reportedly did not align with the vision of the film’s producers.

For her subsequent audition, Melchior adopted a darker, more eccentric portrayal of the character, which resonated with Gunn and ultimately led to her casting.
