Filming has started on Only Child, a new six-part comedy from BBC Comedy and BBC Scotland made by Happy Tramp North, starring Gregor Fisher (Rab C Nesbitt, Love Actually) and Greg McHugh (The A Word, Fresh Meat, Gary Tank Commander) as father and son. McHugh plays Richard, an only child and budding actor, who travels back to his family home in Scotland to look after his ageing and wilful dad Ken, played by Fisher.
