The former s> which details Robert's defence of OJ Simpson in the latter's murder trial.
David – who played Ross in Friends - told The AP that he was able to chat to Kris about her ex-husband ahead of filming.
We presume this means she's onboard with the TV show?
David said: "I was lucky enough to speak to [Kris] for a few hours who was very generous with her time. I thought, `Who better to tell me who Robert was as a husband and a father than her?' and it's been a very exciting process so far."
Kris was married to Robert from 1978 until 1991. They had four children together: Kourtney, 35, Kim, 34, Khloe, 30, and Rob, 28. She was divorced from Robert by the time he represented OJ in the 1995 murder trial. As well as being married to Robert, Kris was also friends with OJ's ex-wife Nicole Brown Simpson.
She will be played by Legally Blonde actress Selma Blair.
