4. Mike Newell
Mike Newell isn't a household name, but he directed a small 2005 film you may have heard of called Harry Potter and the Goblet of Fire. Other films on his resume include Donnie Brasco, Mona Lisa Smile, Four Weddings and a Funeral, and Prince of Persia: The Sands Of Time. Prince of Persia: The Sands of Time may not have been the runaway success that Disney was looking for, but its problems arguably didn't stem from Newell's direction. In fact, Newell utilized a few key things in that film that he could bring to Aquaman, including the costume, character, and set designs as well as the high-adrenaline action scenes. Plus let's not forget his work on The Goblet of Fire, one of the better Harry Potter adaptations, that delivered some of the franchise's most gripping and moving character moments as well as some of the series' most memorable and big-scale action set pieces, including one extended sequence that takes place underwater. Newell executed those underwater scenes perfectly, and showed that an underwater-heavy film like Aquaman would certainly be possible on a large scale. His underwater scenes were well paced, well shot, and incredibly convincing, so he could easily bring those skills to DC's Atlantean blockbuster.
