I think Johnson may have done this because the new footage (which you can check out here), looks a helluva lot more convincing than that first look. Discontent with the believability of GHOST RIDER could kill this flick before it even gets a chance to hit theaters, so I imagine all those involved with the film will be working overtime to convince fans that the final F/X are going to kick ass.
Based on this clip, I’d say they’re clearly on the right track. Now if we could just get some Eva Mendes footage, preferably of her in motorcycle leathers.
