Dear Arthur, Love John, by West End playwright Roy Smiles, charts the relationship between Dad's Army stars Arthur Lowe and John Le Mesurier and focus on the creation of the beloved TV series.

It is 1982 and as John writes to Arthur to say how much he misses him, the story flashes back to Dad's Army: the first read through, the reaction to getting 21 million viewers, Lowe's hatred of being recognised by the public, the rivalry between John Laurie and Arnold Ridley, Lowe's hostility to Clive Dunn and socialism; the affection Le Mesurier had for them all, particularly Jimmy Beck, and how, after initial snobbery about the show, the cast came to realise it was the best time of their lives.

Lowe and Le Mesurier were men of wildly different temperaments, yet bonded while working together on the series over the course of its nine-year run and became fast friends. Anton Lesser will play John Le Mesurier in the drama, while Robert Daws will play Arthur Lowe.
