RTÉ is commissioning a new drama on the disappearance and murder of the Tipperary DJ known as “Mr Moonlight,” with Brendon Coyle (of Downton Abbey) set to star as Bobby Ryan. Multiple outlets report that Coyle’s casting has been confirmed for the series.

The project is based on one of Ireland’s longest-running murder cases, which involved the disappearance and subsequent killing of Mr Moonlight. Coverage characterises the story as an RTÉ drama centred on the investigation and events surrounding the case. Outlets differ mainly in how they frame the announcement—some emphasise the “first look” casting news, while others highlight that the drama is a commissioned adaptation of a long-tried murder case.

All reports agree the production will air next year, and that Bobby Ryan is Coyle’s role in the programme.
