Christian Bale visits the hospital caring for the some of the victims of the Aurora movie house shooting.
Carey Rottman, one of those injured in Friday's shooting at a theatre showing The Dark Knight Rises, posted two photos of himself with Bale on his Facebook page. Hospital staff also posted a Facebook photo of the actor with some staff members.
An online campaign had urged Bale to visit survivors of the shooting.
After visiting The Medical Centre of Aurora, Bale and his wife Sibi Blazic stopped by a makeshift memorial to the victims near the movie theatre. He walked among the 12 crosses erected for each of the slain victims. Many people there didn't realise who he was or chose to leave him alone.
A Warner Bros spokesperson 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."
US President Barack Obama and members of the Denver Broncos also have made hospital visits to some of the survivors.
Comic postponed
The latest issue of a Batman comic due to hit stores this week will be postponed in light of the shooting rampage, DC Entertainment said on Tuesday.
"Out of respect for the victims and families in Aurora, Colorado, DC Entertainment has made the decision to postpone the release of Batman, Inc #3 for one month because the comic contains content that may be perceived as insensitive in light of recent events," DC Entertainment said in a statement.
While DC Entertainment, a division of the Warner Bros Entertainment, did not divulge the exact nature of the "insensitive" imagery in the latest Batman, Inc, Chris Burnham, the illustrator of the series, posted on Twitter that the delay was "due [to] some grim imagery that would seem wholly inappropriate given the Aurora killings".
He added there was a specific scene "that made DC & the whole Bat-team say 'yikes'. Too close for comfort."
Batman, Incorporated, also known as Batman, Inc, is one of 52 comic books, which includes other Batman-related series, that DC Comics publishes every month. It was re-launched in May this year and was due to release its third installment on Wednesday.
The new issue date will be August 22.
