Speaking to DS, the Brit filmmaker admitted that he had considered putting his frequent leading man Dyer in the Gary Oldman role from Alan Clarke's 1988 TV movie, but decided to cast unknown Paul Anderson as football hooligan Bex instead.
"Because I've worked with Danny Dyer a lot and I was known for making films with Danny, obviously we made The Football Factory together, he could've played Bex. It's the only part he could've played, you couldn't put him in a minor role somewhere," Love explained.
"The Firm was kind of a fill-in project [for The Sweeney], it was not a big-budget film, a sort of 'just get on with it now'. I always thought that if you make a film for a small amount of money you can put who you want in it. I just thought the best thing to do is put in people you haven't seen before."
The Firm is out on DVD and Blu-ray now.
