Witnesses said a man wearing a gas mask opened fire after tossing a tear gas canister at a midnight showing of The Dark Knight Rises.
A 24-year-old man was arrested in a car park nearby in possession of a rifle, handgun and knife.
One other gun was recovered from the theatre, which is in Aurora.
Police have revised down the death toll from 14. They said about 50 people had been shot, including the deceased.
FBI sources named the gunman as Aurora resident James Holmes. They said no terrorism link had been established.
US President Barack Obama has spoken of his shock at the incident, which began at about 00:30 local time (06:30 GMT) at the Century 16 cinema complex.
The suspect told police explosives were at his home.Police chief Dan Oates told reporters that an apartment block in the north of Aurora had been evacuated as they investigated that information.
He said the shooting was "a horrific event".
"Witnesses tell us he released some sort of canister," he added. "They heard a hissing sound and some gas emerged and the gunman opened fire.
"The shooting apparently went on for some time."
Ten people were killed at the cinema and two others died later in hospital of their wounds.
A three-month-old baby is among 21 people being treated for gunshot wounds at the University of Colorado hospital. The oldest victim there was 45 years old.
Twelve people were taken to the Medical Center of Aurora with gunshot wounds, ranging from minor to critical condition. They were aged from 16 to 31.
Six victims, the youngest of whom was six years old, were being treated at Children's Hospital Colorado.
The Denver Health hospital had seven victims, one in a critical condition.
One witness said a man in a bullet-proof vest and riot helmet had been "slowly making his way up the stairs and just firing - picking random people".
