Dan Aykroyd has sold his millionth bottle of Crystal Head Vodka. The “Ghostbusters” and “Blues Brothers” star teamed with artist John Alexander nearly two years ago to create the skull-shaped bottle for what’s touted as the world’s purest vodka, distilled in Newfoundland. The brand has racked up nearly $50 million in North American sales. Aykroyd is also busy voicing Yogi Bear for the Warner Bros. animated feature.
