Dalek (A Life in the Day of a Doctor Who Production)

Sid Manley was a Dalek who once got a "nudie" photo job with Katy Manning for a girlie mag.

He used this occasion as an example to dispel the general opinion that Daleks were a bunch of mean-spirited no-goods, instead drawing attention to their amazing loyalty to one another. Indeed, one Dalek offered to be Manley's stand-in, another offered to hold his coat and a third offered to make the tea. (NOTVALID: Doctor Who? 220)

The Third Doctor later asked Jo, camera in hand, if he could get "just a few snaps" with her and the Dalek. (NOTVALID: A Moment from 'Doctor Who' 3)

Behind the scenes
Manley is a reference to Katy Manning's real world nude photoshoot with a Dalek for the glamour magazine Girl Illustrated. The character's name is a reference to Tym Manley, who interviewed Manning in that publication.

Manning's photoshoot was later referenced in valid media as well. In the 2013 comic story Unnatural Selection, Adam Mitchell has possession of an indistinguishable blonde girl who is posing naked with a Dalek.
