Inspired by the true story of a fraudster and murderer who preyed on tourists travelling through Asia in the 1970s, The Serpent is the latest true crime drama being binged in lockdown. Starring Tahar Rahim as killer Charles Sobhraj, and Jenna Coleman as his lover and accomplice Marie-Andree Leclerc, the eight-part drama is currently showing on BBC1 and BBC iPlayer. "A hidden darkness on Asia's hippie trail - the twisting, real-life story of a murderer, thief and seductive master of disguise," is how the BBC bills it, and reviews have praised Rahim's performance as the "ice-cold" killer who became one of Interpol's most wanted men.
