Apparently much of Diane Lane's 'electric performance' was cut due to running time constraints. At a press conference director Peter Landesman and Liam Neeson both championed Diane Lane's performance saying how devastated they all were (especially Lane herself) that so much of her superb performance was left on the cutting room floor. There were hints that these scenes may be included as 'deleted scenes' or as an 'extended cut' on the home video release of the film.
This is the second time Peter Landesman has worked with either Scott Free or Playtone productions. The other Playtone movie Landesman directed was Parkland (2013) and the other Scott Free movie was Concussion (2015).
