Re: Wanda Ventham cameo in SHERLOCK Season 3 Episode 1
Wanda Ventham (and husband) were in last night's Sherlock episode too - season 3, episode 3: His Last Vow.
The showrunner, Stephen Moffat, has kind of made the whole Sherlock team a family affair. Apart from Benedict Cumberbatch's real parents playing Mr and Mrs Holmes, Stephen Moffat's wife, Sue Vertue, is one of the producers of Sherlock; her mother (Beryl Vertue) is a Sherlock exec producer. Amanda Abbington plays Mary Watson - she is Martin Freeman's (Watson) wife in RL. The young Sherlock portrayed in last night's episode (His Last Vow) was played by Moffat and Vertue's son, Louis.
