Annapurna Pictures partnered with Menchie's Frozen Yogurt for a promotion celebrating the theatrical release of MISSING LINK. 

The promotion consisted of The Menchie's and Missing Link Adventure Sweepstakes. 

One lucky Grand Prize winner won a trip to the Grand Canyon for up to four people. The trip package included up to four round trip airline tickets and hotel accommodations that included three standard room nights at the Grand Canyon Railway & Hotel located in Williams, AZ and two standard room nights at the Maswik Lodge North located in the Grand Canyon National Park. Also included were up to four tickets to the train experience which travels daily from the Grand Canyon Railway & Hotel to the South Rim of Grand Canyon National Park. A check for $250 was also sent to the Grand Prize Winner to help cover any additional expenses. 

The sweepstakes kicked off on April 1 and ran through the end of April 2019. During that period, all Menchie's customers automatically received one entry into the Sweepstakes when they used their registered Menchie's loyalty card. Those that did not have the card were invited to stop into any location and register for for their My Smileage card. 

Participants could also enter online at Menchie's website.
