A very tall comedian and a very short comedian with similar surnames are two of the subjects of the new run of BBC1's hit genealogy series Who Do You Think You Are?

Comedian Greg Davies and comedy actor Warwick Davis will both have their family trees scrutinised by the experts.

Royle Family star Ricky Tomlinson's roots will also be uncovered in the new series.

Other subjects include Sophie Raworth, Danny Dyer, Amanda Holden, Liza Bonnin and Sunetra Sarker.

Who Do You Think You Are? returns to BBC1 this autumn.
