Given their track record, you might think that Dick Clement and Ian La Frenais would be spared the struggles that lesser screenwriters go through to see their writing on screen. But this, it turns out, would be naive. Clement and La Frenais may have written some of the best-loved programmes in British television history: Auf Wiedersehen, Pet; Porridge; The Likely Lads; Whatever Happened to the Likely Lads? Their CV may contain the huge hit film The Commitments — as well as more recently acclaimed TV dramas like The Rotters’ Club and Archangel.
