New Harry Potter set videos and photos offer fans a better look at Nick Frost's Hagrid and Dominic McLaughlin's Harry.

The actors playing Harry Potter and Hagrid in HBO’s new series were spotted filming for the first time in London on Monday. Dominic McLaughlin, 11, got into costume as the beloved titular wizard with a collared sweater, a coat, jeans and a backpack.

There’s a lot of big emotions surrounding HBO's "Harry Potter" series. Between the fact that there’s already one successful book-to-screen adaptation and the controversy surrounding J.K. Rowling, there is some trepidation when it comes to the show.
