Michael B. Jordan and Hailee Steinfeld make sin look good … ’cause they both stunned at the premiere of their new movie “Sinners.”

The two stars hit up Manhattan’s AMC Lincoln Square on Thursday for a first look at their highly anticipated new movie before going to the after-party at Aqua New York … and, in exclusive video obtained by TMZ, MBJ looked right in his element — grinning wide and chatting up everyone at the premiere.

He’s a natural in a crowd … laughing it up with some, chatting quietly with others — and totally captivating those around him. Not exactly a shock given he’s been one of the biggest stars in the world for a while.

Hailee wasn’t the center of attention in the clip … but, she did pose for pics and chat with a few acquaintances at the event — while wearing a fiery red gown.

Also at the premiere … writer-director Ryan Coogler, Miles Caton, Jack O’Connell, Wunmi Mosaku, Li Jun Li, Jayme Lawson, Omar Benson Miller, Delroy Lindo and more.

“Sinners” follows Jordan — playing twin brothers — who hope to leave their troubled lives behind by going back to their hometown … only to find a darker evil waiting for them.

The movie was set for release last month but had to be delayed due to post-production issues … stemming mainly from shooting the movie on film.
