A Warner Bros spokeswoman told The Denver Post that Bale was representing himself, not the movie studio.
Bale, who stars as Batman in The Dark Knight Rises, previously issued a written statement saying: "Words cannot express the horror that I feel. I cannot begin to truly understand the pain and grief of the victims and their loved ones, but my heart goes out to them."
President Barack Obama and members of the Denver Broncos also have made hospital visits to some of the survivors.
The movie's director Christopher Nolan recently released a statement expressing his "profound sorrow" at the tragic events.
He said in a statement: "I would like to express our profound sorrow at the senseless tragedy that has befallen the entire Aurora community.
"I would not presume to know anything about the victims of the shooting but that they were there last night to watch a movie.
"I believe movies are one of the great American art forms and the shared experience of watching a story unfold on screen is an important and joyful pastime.
"The movie theatre is my home, and the idea that someone would violate that innocent and hopeful place in such an unbearably savage way is devastating to me."
Nolan concluded: "Nothing any of us can say could ever adequately express our feelings for the innocent victims of this appalling crime, but our thoughts are with them and their families."
Warner Bros, which described itself as "deeply saddened," cancelled the premiere in Paris, France and upcoming promotional appearances by the cast have been postponed.
