Estrella89san has found this fabulous sit-down interview of Tom, Bonnie, Oliver and James on Allocine.fr from when they were in Paris for the Fnac Harry Potter press event. I call it fabulous because it was not at the signing but a scheduled sit-down portion (and Tom’s wearing a different outfit!). They all answer a series of questions about HP, and yes, Tom even discusses hiding behind his hair (or lack thereof). 🙂
