PattinsonPost interviewed Sonya Gonzales, the mom of the WFE kids. Here's an excerpt.
(...)Sonya, her husband and the boys headed out to the site of the filming very early one morning. Her boys really had no idea who Robert Pattinson was, but her oldest was so excited to get a chance to meet the elephant, Tai. Her youngest son was pretty happy just to get to do whatever his older brother was doing. When the boys went to the trailer to get their hair cut, they ran into Robert Pattinson. As they were introduced, the actor smiled and joked about, ‘oh more kids’, because he’d already met the three little girls who would be playing his daughters in the film.
Shortly after the filming of her sons, Sonya and her husband had the opportunity to join the cast for the cast party. “I was struck by how ‘down to earth’ and approachable both Robert Pattinson and the director of the movie, Francis Lawrence, were.” She chatted with Francis first and she remembers him as being ‘super nice’. She said when she mentioned how nice it would be to see Robert in a different movie other than Twilight, he told her he was ‘proud’ of the job that Robert was doing in the film. Her memories of talking with Robert are blurry and she recalls the whole experience as being ‘surreal’. “He’s so much taller than I am and he was dressed like a regular guy with a ball cap on. I didn’t know he was from England until he spoke to me.” Once she heard him speak, she said she asked him about his impressions of the US, where he grew up in England and how often he gets to see his family. She also said he was ‘very sweet’ and he didn’t hesitate to let her husband take a picture of her with him.
Also, Sonya almost managed to make it in the film as Reese's body double.
