Javier Botet has Marfan syndrome, which made him very tall and thin (2 meters high). He is an owner of extremely long fingers.
Those features allow him to be the best known Hollywood actor playing monsters. He is fantastic at trying on different costumes and make up and giving the audience a real scare.
