Spock has a mustache and sideburns. This wonderfully bad fan film was made by Ray (who I gather is an expert on Betamax recordings) in 1971 for a TV production class at Ohio State University. He used a 1-inch open reel video tape and earned an A- for the project.
My vote goes to losing the mustache but keeping the sideburns. Sideburns are rarely a bad fashion choice.
