With storylines concerning gun violence, insecure employment and undocumented immigrants, David Hare’s first foray into episodic TV is nothing if not relevant. Collateral is one of those dramas where nobody smiles, it’s always raining and no good deed goes unpunished. In tonight’s opener, a pizza delivery man is shot dead and Carey Mulligan’s DI Kip Glaspie must explore London’s underbelly in search of clues. At this stage, it’s a rather one-note wallow in misery; let’s hope more light and shade is soon forthcoming. Phil Harrison

With bitcoin leading the virtual economy, there are many questions surrounding the blockchain-based bucks. It is unregulated, so why do so many regard it as a secure investment? And is the bubble now bursting? Spencer Kelly investigates. Mark Gibbings-Jones
Mike “Doctor Foster” Bartlett’s acid potboiler stars Adrian Lester as a successful and smooth surgeon whose teenage patient dies on the operating table. Grief combines toxically with class envy as he is blamed by the boy’s dad, John Simm. It is a stalker drama where everyone has to act irrationally to help keep the story alive. Continues tomorrow. Jack Seale

While most of us agonise over whether to pay extra to preselect a seat, first-class travellers are the beneficiaries of airlines battling for their business. A documentary that takes us into a rarefied world where Singapore Airlines is spending $850m to create a suite for the super-wealthy. Jonathan Wright

After last week’s exposition dump, the revivified X-Files shifts into action mode with Mulder and Scully on the run from a shady and very Russian-sounding military contractor. Can they piece together the connection between the return of an old ally, phone phreaking and a vintage NSA listening post in New York? Graeme Virtue
It is tough to predict what will work on TV. Exhibit A: the third series of this show, in which minor celebs play old-school video games against each other. Catnip for the hidden hordes of the callus-thumbed, but a little more trying for the casual. Tonight: Gregg Wallace (strategy) v Jodie Kidd (reflexes). John Robinson

Amma Asante’s 18th-century costume drama is based on the true story of Dido Elizabeth Belle, an African slave brought up in London by her great uncle, Lord Mansfield (Tom Wilkinson). It is a finely worked tale that addresses issues of slavery, race and class, and Gugu Mbatha-Raw is luminous in the title role. Paul Howlett
