In the role, Pascal's face may be hidden for the most part behind The Mandalorian's face armour (someone already appears to have taken that job for the promo images), and his activities appear to be of the roaming the universe shooting things variety.
This is Disney's official synopsis:
"After the stories of Jango and Boba Felt, another warrior emerged in the Star Wars universe. The Mandalorian is set after the fall of the Empire and before the emergence of the First Order. We follow the travails of a lone gunfighter in the outer reaches of the galaxy far from the authority of the New Republic...."
Other exciting names working on the show include directors Taika Waititi and Bryce Dallas Howard, with Jon Favreau looking after the series as a whole.
The Mandalorian doesn't have a premiere date yet, but with filming underway, we can expect it to arrive on Disney+ next year. For everything else arriving on the service, go.
