“Nicola and I, being new to this Hollywood way of filmmaking, supported each other an awful lot. We have a great relationship with one another. Mark Wahlberg was an awful lot of help to us too, and Stanley Tucci and Kelsey Grammer,” Jack said to Paste magazine about his experience filming. “Just to see these guys, these veterans of the industry, working in their own environment and seeing how they relate to Hollywood and how Hollywood relates to them informs our work ethic and teaches us how to proceed with our careers.”
