Today at the Hollywood Walk of Fame star ceremony for celebrated film composer Hans Zimmer (he scored this year’s Inception), he reminisced about his dear friend and publicist Ronni Chasen, who was infamously and mysteriously shot and killed last month, dedicating the star both to her and to his mother who died last year. Inception auteur Christopher Nolan was present at the ceremony as well (he can be seen at the end of the video, posing for photos with Zimmer).
