How many Star Trek films did Leonard Nimoy appear in as Spock?

Leonard Nimoy brought his pointy ears and famous eyebrow raises to eight Star Trek films between 1979 and 2013, completely skipping the Next Generation era movies. While he initially declared he was done with Spock after 1991's "Star Trek VI," he couldn't resist coming back for two more appearances in the reboot timeline, proving you can never really retire from being the galaxy's most logical alien.
