Gibley was in Venice on Tuesday for the premiere of his film "The Armstrong Lie," in which he salvaged the 2009 footage meant for a comeback movie and added interviews with Armstrong after the stunning disclosure.
Gibley said that Armstrong "to some extent, is always a curator of his own myth and his own story" and once he realized that people no longer idolize him the same way "I think he wanted to spin it."
Still, Gibley maintains that Armstrong "was more honest" in the later interviews.
