AURORA, Colorado — Batman actor Christian Bale paid a low-key visit Tuesday to Aurora, Colorado to comfort victims of last week's shooting massacre, which occurred during a screening of his latest film.

Pictures posted on Twitter showed the Welsh-born actor at the Medical Center 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.

Rottman posted two photos of himself with Bale -- who won a best supporting actor Oscar in 2011 for his work in "The Fighter" -- on his Facebook page.

The 27-year-old Rottman said he suffered a gunshot wound to the leg in Friday's attack.

"What a surprise! 19 Swedish staff members met actor Christian Bale today @ TMCA! More details soon," read another tweet from the Swedish Medical Center with a photo of Bale wearing a black T-Shirt and posing with medical personnel.

On Saturday, Bale said through his publicist: "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."

Another of the film's stars, Anne Hathaway, said Sunday: "My heart aches and breaks for the lives taken and altered by this unfathomably senseless act. I am at a loss for words how to express my sorrow."

James Holmes, 24, is accused of shooting 12 people dead and wounding 58 more at a cinema in Aurora, outside Denver, as young moviegoers packed the first midnight screening of the latest Batman film, "The Dark Knight Rises."

In the film, Bale plays Bruce Wayne -- who dons his cape and mask to become the Caped Crusader -- and Hathaway plays Selina Kyle, whose alter ego is Catwoman.
