9 Game Of Thrones Actors Who Were Also In Harry Potter

3. Natalia Tena

Osha and Tonks, both characters known by just one name (honestly, don't call her Nymphadora), both secondary characters who are really well-liked by fans and have their own important part to play in things, and of course both played by Natalia Tena. Osha is a wildling who fled to Winterfell from North of The Wall, who had some knowledge of the Others and formed a close relationship with Bran and Rickon.

Having disappeared for 3 seasons with Rickon, Osha unfortunately reappeared and was murdered by the delightfully awful Ramsay Bolton while trying to assassinate him. At least she tried.

Tonks, meanwhile, was a member of the Order of the Phoenix. She was one of the younger members, and her bright personality (and hair) inject a spark of lightness into proceedings as the series turns increasingly darker, and her and Lupin make an excellent couple until their tragic (and sometimes overlooked) deaths in Death Hallows.
