Several of the names in the series are puns. Kieren's last name is Walker, which is a term sometimes used to refer to zombies. Amy's last name is Dyer, referencing her deceased state. The show is set in the fictional village of Roarton, which sounds like "rotten".
In January 2015, BBC Three announced that In The Flesh would not be renewed for a series 3 due to cuts to its budget for its final year as a televised channel.
Anyone who was a zombie during the 'rising' and got the medical treatments are diagnosed with PDS (Partially Deceased Syndrome).
The street address number of the Walker's house is 51, as in Area 51.
