They join Tahar Rahim (The Looming Tower) who will play real life serial killer Charles Sobhraj, one of the most evasive criminals of the 20th century.
The series, written by Richard Warlow and Toby Finlay, follows Sobhraj’s murderous spree, which was estimated to have taken place between 1975 and 1976 across India, Thailand and Nepal’s ‘Hippie Trail’.
He was the chief suspect in almost 20 unsolved murders of young Western travellers during this time and by 1976 was Interpol’s most wanted man, with arrest warrants on three different continents.
The new series will see Olivia Colman and Tobias Mezies take over the reins from Claire Foy and Matt Smith as The Queen and the Duke of Edinburgh.
The upcoming series will cover The Queen’s reign from 1964 up to 1977 and see the beginning of Prince Edward’s life, the marriage of Princess Anne and Captain Mark Phillips and the celebrations of The Queen’s Silver Jubilee.
With so many shows available, viewers are spoilt for choice.

Celebs Go Dating, series seven
From Monday 5th August, E4, 9pm
Is it just me, or does this account of the relentless march of Sky feel less like a window into the “future of entertainment” and more the TV equivalent of ancient history?
There are glorious deeds and all-conquering heroes. Step forward Jeremy Darroch, and the man who appointed him CEO of Sky, James Murdoch. Not forgetting the tragic fate of doomed and misguided rivals: hold your heads in shame, Setanta and a host of others.

Stranger Things, season three
From Thursday 4th July, Netflix
With a release date set for U.S Independence Day, the return of Stranger Things for season three is going to be a big event and one fans have been waiting a long time for.
Creators The Duffer Brothers have promised a darker, funnier series that will be worth the wait.
The hub will contain 14 sound studios, workshops and office spaces, and is part of Netflix’s long-term commitment to the UK.
Netflix will produce new and existing TV and feature films at the Pinewood owned studios, as they expand their UK network.
In the last year over 25,000 cast, crew and extras have worked on nearly 20 Netflix originals and co-productions across Britain.
Further speakers announced include Karen Blackett OBE, Chair of MediaCom UK; Howard Davine, Executive Vice President, Business Operations, ABC Studios; Sir Lenny Henry, actor, comedian and diversity campaigner; Tim Hincks, Co-CEO of Expectation; Jane Turton, CEO of All3Media; and Linda Yaccarino, Chairman of Advertising and Client Partnerships, NBCUniversal.
The 2019 event, which is set to take place at King’s College in Cambridge from the 18-20th of September, is this year entitled “Content, Consumers, and everything in between”.
Four years in the making, the film has been described as “Gravity meets Touching the Void – 100 metres underwater” and tells the story of a commercial diver, Chris Lemons, who is stranded on the seabed with five minutes of oxygen left – but no chance of rescue for more than half an hour.
