Google is known for periodically offering free goodies to Chromecast owners. Most recently, Google gave three free months of HBO Now with purchase of a Chromecast. In the Chromecast Ultra's first promotion, you can grab a free copy of the Ghostbusters remake in 4K from Google Play Movies. It may not be the best-performing movie this year, but you can't beat free.

The offer is available to anyone who has purchased and activated a Chromecast Ultra before December 31st, and you can redeem the offer until April 30. As you might expect, this is only valid in the United States and Canada.
