Costumes and makeup thumb|left|alt=A collage of photos depicting the application of makeup and prosthetics to Danny DeVito's face to play the Penguin|To transform into the Penguin, Danny DeVito wore a combination of prosthetics and makeup which covered much of his face. Bob Ringwood and Mary E. Vogt were the costume designers. They refined the Batsuit to create the illusion of mechanical parts built into the torso, intending Batman to resemble Darth Vader. Forty-eight foam-rubber Batsuits were made for Batman Returns. They had a mechanical system of bolts and spikes beneath the breast plate to secure the cowl and cape because "otherwise, if [Keaton] turned around quickly the cape would stay where it was", due to its weight. Costumer Paul Barrett-Brown said that the suit had a "generous codpiece" for comfort, and initially included a zippered fly to allow Keaton to use the bathroom; the actor declined, however, because it could be seen by the camera from some angles. As with the Batman costume, Keaton could not turn his head; he compensated by making bolder, more powerful movements with his lower body.
