It's always a good day when someone new is welcomed to Doctor Who – and now it's Varada Sethu's turn!


The actress will star in season 15, which is set to air in 2025, alongside Ncuti Gatwa (the Fifteenth Doctor), taking over from Millie Gibson.

Gibson, who was previously spotted filming with Jonah Hauer-King, will still appear in the series but with a smaller role.

Sethu hasn't addressed the report just yet but she's been seen filming with Gatwa for a 1950s American adventure, and we're already obsessed with her style.

The actress is certainly no stranger to sci-fi, so if you want to catch up on where you might have seen her before, read on!

Here's everything you need to know.

Who is Varada Sethu?

Sethu is an actress who has already made her mark across TV and film before coming to Doctor Who.

Born in Kerala, India, she moved to the North East of England at a young age with her family, including her twin sister Abhaya.

She grew up as part of the National Youth Theatre and, after studying veterinary medicine and physiology at university, continued with her acting dreams at London's Identity School of Acting.

Sethu's most prominent role has so far been Cinta Kaz in Disney Plus's highly acclaimed Star Wars series Andor.

Previously opening up to The Hindu, Sethu chatted about her character Cinta, saying: "She was written as someone who does not speak a lot, but when she does, she holds a presence.

"I think Vel (played by Faye Marsay) was described in the script as someone who is physically powerful and commanding, and Cinta is the one who looks meek, and may not be capable of violence. So, it's a shock when people see her in action, which also ties into the ideology of women slipping under the radar."

In 2017, she played Aisha in the popular drama Doctor Foster, before landing a starring role in BBC apocalypse thriller Hard Sun.

In 2019, Sethu appeared in the series Hanna, before starring in Strike Back from 2019 to 2020. Going back to sci-fi, Sethu appeared in Jurassic World: Dominion in 2022. The same year, she appeared in the film I Came By, and played Cinta in Andor.

Most recently, Sethu has played DC Harper Weston in Annika and Rani Toor in Mrs Sidhu Investigates – and now she's filming season 15 of Doctor Who!
