Hugh Dennis joins Sam Heughan, Eleanor Tomlinson in The Couple Next Door

Dennis and Robbins will play a couple, Alan and Jean Matterson, who are neighbours to the newcomers, Deadline reports.

Though they soon start to feel unwelcome in their new home, Evie and Pete find some comfort when they strike up a friendship with the couple next door, traffic cop Danny (Heughan) and his yoga instructor wife Becka (Jessica De Gouw).

Things get messy from there, however, with the synopsis reading: "As time goes on, these two couples get increasingly close to each other and one fateful night, become sexually entangled in a way that will change their lives forever…"

A co-production between Channel 4 and STARZ, The Couple Next Door is due to air in the UK this year and in the US in 2024.

And everything that ensues there."

He went on to praise his "amazing" co-stars.
