Johnny Depp's eccentricities extend beyond a propensity to show up at British elementary schools dressed in pirate garb. The actor is part of a small segment of the population that can't process three-dimensional effects in movies, a malady he refers to by its formal name: "weird eye." In fact, he's likely to skip tomorrow's global premiere for the fourth Pirates installment (aka Stranger Tides), which was filmed in 3D. A pity, since shooting films with multiple cameras (a prerequisite for 3D) reportedly makes nailing shots all the more challenging. At least he can take comfort in the fact that he'll never suffer the pangs of a 3D-induced headache while watching his bank account swell.
