The 43-year-old, who has two Emmys and a Golden Globe to his credit for his performances in "American Crime Story: The People v. OJ Simpson" and NBC's "This Is Us", said in a video posted on his official Twitter account that he will be making his show debut in the upcoming third season.
"I'm beyond excited to share some pretty marvelous news... #MrsMaisel, I'm coming for you! @MaiselTV @PrimeVideo," he wrote in the caption.
In the video, the actor said he is "Eastward bound".
"I'm going to do a little TV show, maybe you've heard of it, 'The Marvelous Mrs. Maisel'. The Palladinos were kind enough to write a little something for your boy, and I said yes. So, stay tuned. I'm getting together with Midge and it's going to be awesome," he added.
The actor, however, did not reveal the details of the character he will be playing on the show.
Brosnahan and Brown have previously expressed their desire to work together on the series.
On the sidelines of the SAG Awards in January, Brosnahan had Brown's red carpet interview and urged him to come aboard her show.
