Sebastian Stan sports all-black outfit to continue filming A24 thriller Sharper in NYC with Julianne Moore

The Falcon and the Winter Soldier action star Sebastian Stan was still hard at work filming A24 thriller Sharper in Manhattan's Upper East Side on Tuesday.

The Romanian-born, New York-raised 39-year-old - who plays clever conman Max - flashed a smile while standing beside a car with Apple AirPods in his ears.

'Max is known for carrying out complicated plans and making away with large sums of money,' reported Deadline.  

'In the film, he's pulled into another scheme.'

Sebastian's head-to-toe black attire consisted of a bomber jacket, sweatshirt, skinny jeans, and unzipped combat boots selected by costumes coordinator Emily Bellomo.

On September 22, Stan started work on Sharper shot by DP Charlotte Bruus Christensen and helmed by Emmy-winning director Benjamin Caron (The Crown), who also has a role in it. 

Joining the What If... guest star on the set Tuesday was Oscar winner Julianne Moore, who also plays a con artist and executive produces the movie with her babydaddy Bart Freundlich. 

The flame-haired 60-year-old shared a behind-the-scenes, on-set selfie on Tuesday captioned: 'What am I doing? Pretty sure I forgot something.'

Sharper - premiering in theaters and globally on Apple TV+ next year - also features John Lithgow, Briana Middleton, and Justice Smith. 

Sebastian and his Gym Mafia buddies will take part in The Empire State Building Run-Up next Tuesday in order to raise funds for Equity Design.

Equity Design is a program that trains '150 teachers on how to use physical activity to enhance learning and impact the health of over 4,500 Bronx youth.'

Gym Mafia has already exceeded their $20K goal with a total $22,733 raised on their GoFundMe page as of Tuesday evening.
