Continuity mistake: After Wormtail performs the Avada Kedavra curse and then raises the "bone of the father," he places Voldemort's wand inside the left side of his coat, before he slices off his right hand. When Voldemort says, "My wand Wormtail," Wormtail retrieves the wand from the right side of his coat. (01:56:00 - 01:57:40)
Answer: Not at all. In fact, David Heyman made the decision for his eyes to be blue in the films for him to be more scary! They felt that his red eyes in Sorcerer's Stone did not show enough emotion to make him an evil character. It was felt in Goblet of Fire that the light blue eyes would be perfect to show his evil in the moonlight, and they kept it on for later films.
