Aurora, Colorado - Actor Christian Bale on Tuesday paid a low-key visit to Aurora, Colorado, to comfort victims of last week's shooting massacre, which occurred during a screening of his latest film, The Dark Knight Rises.

Pictures posted on Twitter showed the Welsh-born actor at the Medical Centre of Aurora, where 20 of the 58 people wounded in Friday's massacre are still receiving treatment, some of them in critical condition.

“ChristianBale meeting with #Aurora #theatershooting victim Carey Rottman,” read one tweet above a photo of Bale, crouched next to the young man with his arm resting on his chair as the two smiled for the camera.

“What a surprise! 19 Swedish staff members met actor Christian Bale today (at) TMCA! More details soon,” read another tweet from the Swedish Medical Centre with a photo of Bale wearing a black T-shirt and posing with medical personnel.

James Holmes, 24, is accused of fatally shooting 12 people and wounding 58 more at a cinema on Friday in Aurora, outside Denver, as moviegoers packed the first midnight screening of the latest Batman film.
