It is assumed that the weapon from which Baldwin fired was supposed to be loaded with blank cartridges, but this turned out to be not the case.

No charges have been filed against the actor yet.

The filming of the film itself has been suspended. 

In January 2019, Baldwin pleaded guilty to a fight over a parking space.

The court sentenced him to a fine and compulsory anger management course.

Also in 2019, Baldwin announced that he was tired of playing the role of US President Donald Trump on Saturday Night Live.
