The Wrath of Khan
The second Star Trek feature movie. Based on the episode Space Seed from the original television series where Ricardo Montalban portrayed evil genius Khan. Many fans consider Wrath as the strongest of all the Trek franchise movies produced.
Credit is given to Montalban's performance, the relaxed ensemble cast of Shatner, Spock, and McCoy, intense dramatic action and a well paced script as the key reasons for this movies success.
