Last week, the cast of Star Trek Beyond appeared in a set video to announce their Omaze contest, where one lucky fan will win a walk-on role in the sci-fi sequel. While that lucky winner will be announced at a later date, the contest is also selecting weekly winners to become honorary "crew members," the first of which has already been chosen. To kick off the campaign's second week, stars Simon Pegg (Scotty) and his "son" Anton Yelchin (Chekov) appear in another Omaze video, where they announce the first honorary crew member, and give fans a glimpse at one of the new alien masks that will be used in the film, along with a few props.

Nothing was revealed about this alien mask or any of the other futuristic props seen in this latest sneak peek, but there will surely be more opportunities to catch a few glimpses from the set in weeks to come. Last week's featurette gave us a look at cast member Idris Elba on set. There will be five more honorary crew members selected each week through August 23. And since each week benefits two new charities, we can surely expect more behind-the-scenes fun from Star Trek Beyond, from now until the end of August.

Every $10 entry supports nine global organizations each nominated by members of the cast. This week, the campaign is highlighting Time is Precious, nominated by Simon Pegg, which provides children's hospitals with new equipment and Camp Sunshine, nominated by Anton Yelchin, which is an amazing summer retreat for children with life-threatening illnesses.
