Blacklight is a 2022 action thriller film directed and co-written by Mark Williams. The film stars Liam Neeson as a brooding FBI fixer who becomes involved in a government conspiracy; Emmy Raver-Lampman, Taylor John Smith, and Aidan Quinn also star.

Blacklight was released in the United States on February 11, 2022, by Briarcliff Entertainment. Unfortunately, it struggled both commercially and critically. Despite having a production budget of $43 million, it only managed to gross about $16 million worldwide, making it a box-office bomb. Critics were harsh on the film, and it received overwhelmingly negative reviews, with some calling it one of Liam Neeson's worst performances and movies. The storyline, action sequences, and overall direction were widely criticized, adding to its reputation as a low point in Neeson's career.
