The 26th of May is Peter Cushing's Birthday. The 27th is Christopher Lee and Vincent Price's Birthdays. It's the trifecta of Gothic Horror Icons whose birthdays are only hours apart from each other. Not the same year.
Further note: Peter Cushing and Vincent Price were the basis for Peter Vincent in the original Fright Night, Fright Night Part 2, and Fright Night tie-in comics.
