Clark Tabor, 52, appeared before Judge Lyle McKenzie in Bellflower on one count each of criminal threats and disturbing the peace by offensive language.
His public defender argued against the psychiatric evaluation.
Tabor will be back in court Aug. 8. If he makes $50,000 bail, he will be ordered to transfer his guns, which he legally owns, to a friend or relative.
On Sunday, Tabor was one of several patrons inside the AMC Norwalk 20 to see the new Batman film. According to witnesses, Tabor held his cellphone in the air and yelled, "Does anyone have a gun?" and "I should go off like Colorado," an apparent reference to the mass shooting during the same movie in Aurora, Colo., that left 12 people dead and 58 others injured.
No gun was found on Tabor, the backpack he was carrying or his home.
Tabor was not armed, but was arrested anyway, and taken to Men's Central Jail.
