Create a captivating image of a character similar to a renowned action movie protagonist. The character should be tall, sporting sleek, dark-coloured suit with a polished black tie. His face is stern, eyes focused with determination, and his head is cleanly shaven. Spot him amid an action sequence, gun in one hand, where bullets are flying past. The poster should be richly colourful, showcasing the vibrant hues of a bustling city at night. The style should take inspiration from early 20th century animation studios, emphasizing exaggerated features, vibrant colors, and expressive emotions. Remember to incorporate '# this is MUST HAVE' in a stylish font at the bottom of the poster.
