Kapoor, who will make his digital debut with the untitled Amazon Prime Video series, took to Instagram and posted a short video, tagging Sethupathi and his co-star, Raashii Khanna.
''Waiting on set call me soon @rajanddk... Can't wait to share the frame with @actorvijaysethupathi sorry @raashiikhanna I've got too used to having you around on set,'' he wrote.
Replying to Kapoor, Khanna wrote, ''Everything is excused for Vijay Sethupathi sir.'' ''I had similar emotions today! Ask @rajanddk,'' she added.
The filmmaker duo of ''The Family Man'' fame also commented on Kapoor's post and wrote, ''Shot ready. Let's roll.'' Billed as a quirky drama thriller, the show has been created and written by Raj and DK. It is co-written by Sita R Menon, Suman Kumar and Hussain Dalal.
There has been no official announcement from Amazon on the casting of Sethupathi -- known for performances in Tamil films like ''Master'' and ''Super Deluxe'', for which he won the National Award for best supporting actor.
