The first look trailer for the BBC's upcoming adaptation of best-selling Mayo author Sally Rooney's novel Normal People has been released, giving viewers a first glimpse at the highly-anticipated series.

The 12-part relationship drama stars British actress Daisy Edgar Jones (War of the Worlds, Cold Feet) in the role of Marianne, and Kildare newcomer Paul Mescal in his first television role as Connell.

The trailer gives a hint of what to expect from the show, as we hear Marianne and Connell talk about their relationship over the phone and see snippets from what has happened between them.

The series charts Marianne and Connell's complicated relationship "from the end of their school days in small-town west of Ireland to their undergraduate years at Trinity College".

It is described as "an exquisite and compulsive modern love story about how two people can profoundly impact each other's lives".

Oscar-nominated Room director Lenny Abrahamson and Howard's End's Hettie McDonald are sharing the directorial duties on the series, which will air on BBC Three and BBC One in 2020.

Rooney, who is executive producer on the series, has adapted her novel for the screen alongside playwright and director Mark O'Rowe (The Delinquent Season) and Alice Birch (Lady Macbeth).

Normal People is produced by Dublin company Element Pictures, which previously worked with Abrahamson on Room, Frank and last year's The Little Stranger. The cast also includes Sarah Greene (Dublin Murders, Rosie), Seán Doyle (Metal Heart, Fair City) and Aislín McGuckin (Outlander, The Nephew).

The series will air on BBC One and BBC Three in the spring this year. The exact air date has not yet been announced.
