Yes, but Kirk screamed "Khaann!" as part of the fake-out of Khan; he screamed as if truly marooned underground, despite knowing that he was coming up on his phone call with Spock at the 2-hour mark.
I agree, though, with mos6507 that
TWoK is Shatner's best performance as Kirk among the seven movies.
TWoK was the first VHS tape that a
lot of people bought, because it was the first one with a "reasonable" price; for years afterward, some VHS movies remained costly (often $70-80).
TWoK was the pioneer low-priced tape (about $40) and a successful gamble for Paramount.
