She’s been in the business for 50 years, but Deborah Vance is about to make history as she prepares to launch her late-night talk show in Hacks season four.

Naturally, her co-writer Ava Daniels is right there alongside her.

However, as the cameras get ready to roll, these two fierce comedians are soon butting heads once again – because when are they not?

With these two leading the way, naturally there’s drama going on among the team as well.

Let’s hope they can all keep it together before the director yells action and they go live to the nation. No pressure.
