Nearly IDENTICAL to...
The 1996 film MULHOLLAND FALLS directed by Lee Tamagori. I reaize "Gangster Squad" is based on a book (supposedly) and all that jazz... But damn I couldn't help but be blown away by how similar they seemed.
They played the trailer to this prior to the movie I saw at New Beverly Theater a few nights ago and, while I haven't seen it before, looked AWFULLY familiar, reminding me of a movie I've seen in recent years. That movie being, of course, Fleisher's "Gangster Squad".
And I found it FUNNIER that Nick Nolte is even in both films! And from the trailer, there were even scenes that looked eerily similar in so many ways.
Take a look for yourselves:
