Edward Scissorhands is one of Tim Burtons most beloved works, but it leaves a huge question regarding its time setting. A year after exploring Gotham City in Batman, Tim Burton returned to horror fantasy stories with his unique visual style in Edward Scissorhands. Written by Caroline Thompson from a story by her and Burton, Edward Scissorhands introduces the audience to a one-of-a-kind lead character: a young man created by a lonely scientist who left him unfinished and with scissor blades instead of hands. As a result, Edward (Johnny Depp) lived in isolation at his fathers mansion for years.
