In the upcoming issue of Details magazine, Christian Bale tells us why we’ll never see him in romantic comedies, details his first experience in the Batsuit and his explains his thoughts about “self-destructing on purpose.” Bale also chats a bit about his Dark Knight co-star, Heath Ledger.

“He was incredibly intense in his performance but incredibly mellow and laid-back. Certainly there was this great anarchistic streak to it—just getting dirtier than anybody’s envisioned the Joker before. This character has power because he has no limits—absolutely nothing to lose.”

When asked how Ledger’s death has impacted his view of the film, Bale added, “Naturally it was something I wanted to share with him—and expected to do so. And I can’t do anything else but hope that it will be an absolutely appropriate celebration of his work.”

The Dark Knight opens in theaters on July 18. Until then, Bale lovers can purchase their copy of Details on June 3.
