‘Downton Abbey’ Actress to Guest on ‘Once Upon a Time’ January 2, 2013 News, Once Upon a Time Actress Lesley Nicol, who appears on the international hit ‘Downton Abbey’ as head cook Mrs. Patmore, will be showing up in an upcoming episode of the hit ABC drama Once Upon a Time according to a report at TV Line. Nicol will appear at some point this season as someone who “has a special connection to the Snow White family”. Well, that could be a little more vague, couldn’t it? Suffice it to say, let the speculation begin as to who she will be playing and whether she will be featured in the fairytale world only or in both that world and in Storybrooke. Nicol may have come to prominence thanks in large part to the success of ‘Downton Abbey’, but she has a lengthy resume of work, including appearances in the BBC TV series ‘The Lion, the Witch & the Wardrobe'; the U.K. series ‘Holby City’, ‘Doctors’, ‘Heartbeat’ and ‘Hotel Babylon’ and the made-for-TV movie ‘Marple: A Murder Is Announced’ [among others]. ‘Once Upon a Time’ will return for the remainder of its second season on ABC starting on Sunday, January 6 at 8/7c, [ironically (or not) the same night that the much anticipated return of 'Downton Abbey' airs on PBS].
