Thu Apr 01, 2021 at 10:43pm ET Harrison Osterfield plays Leopold in The Irregulars. Pic credit: Netflix Netflix’s horror-thriller The Irregulars follows a group of troubled teenagers while they investigate the chilling paranormal activity popping up around Victorian-aged London. These assignments are brought to them by the rude and dismissive Doctor John Watson and the unhinged Sherlock Holmes. It’s a creative and original exploration of the infamous Sherlock Holmes stories which preceded the series. One of the main characters throughout the series is Prince Leopold, a hemophiliac 17-year-old who is in love with the street gang’s leader Bea (Thaddea Graham). The character is courageous and adventurous but also resembles a lovesick puppy as he follows his crush around. Playing Leo in The Irregulars is actor Harrison Osterfield.
