It may have been an ordeal to make "In the Heart of the Sea," but Chris Hemsworth and the rest of the cast sure have a whale of a fish tale about the period drama opening Friday.<br />By the end of filming, the Aussie actor didn't look much like Thor after dropping from 215 to 175 pounds to play one of the starving shipwreck survivors of the real-life whale attack that inspired "Moby Dick."<br />"This was physically and emotionally the hardest movie that I've been a part of," Hemsworth told the Daily News of the film based on the bestselling 2000 book of the same name.<br />"Losing the weight to this length, I just never want to do it again, but it had such an emotional effect on us ... in some small way, we felt like we were doing what these men went through justice."
