He is like, ‘Okay, do the melody.’

Instead, the guys had classic ’90s R&B in heavy rotation.

“We did a lot of R&B,” Brown explains.

“There’s a lot of Sade, there’s a little JoJo going on there.

James knows every song.

On the show, the actors' dynamic is not quite so simpatico.

Brown stars as Xavier Collins, a secret service agent to Marsden’s former U.S. President, Cal Bradford.

OnThis Is Us,the plot was determined by a series of conversations and feelings.

This one has a lot more plot.

Where there’s similarities, is the show delves into a lot of backstories and relationships.

Ultimately, its about families and the lengths we go to take care of one another.

But they’re very different shows with Sterling and I being a little bit of connective tissue.

“We had a blast,” gushes Brown.

Love me some Marsden.”
