When Kelly Asbury (director on Gnomeo and Juliet) asked me to board "Gnomeo prepares for blue raid" sequence, it was completely different scripted. At that time Kelly wasn't sure himself about this sequence and asked me to come up with something new if possible. I remembered a trailer of one of the Rambo movies where we just see a montage of Close ups of Rambo preparing to go to war. I thought it would be an homage to that particular genre of film and at the same time a fun experience to translate it into the Gnomeo and Juliet movie. As a result, Kelly was pleased with the result and so it ended up being used in the film.
