Stewart Granger felt strongly the studio was handing him routine work as punishment for not renewing his contract. Regardless, he dove into quick-draw training for his first role as a gunman, and soon learned how to fan a pistol - at least an empty one. On camera with full-charge blanks, he flubbed the draw and fired it in the holster, burning the entire side of his leg. On another attempt, he impaled his palm on the sharp pistol striker. To top it off, his own horse caused him grief when the well-trained animal nearly threw him after the unfamiliar sound of the camera whirring caused him to spook.
