With production on X-Men: Apocalypse still going strong in Montreal, director Bryan Singer has shared yet another photo through his Instagram account, showcasing one of the massive practical sets. The filmmaker is seen being dwarfed by an Egyptian statue. But he wouldn't offer any details about the set itself or how it fits into the X-Men: Apocalypse story. He did say on his social media account that, "This takes me back to #raidersofthelostark #notallgreenscreen #xmen #xmenapocalypse."

This photo comes just a few days after Bryan Singer posted a photo with Sir Patrick Stewart on the set, which fueled speculation that he would return in a cameo role as Charles Xavier. The actor wasn't seen in costume, but he was watching footage with the director and another filmmaker, Jason Reitman, who was putting together a live read of The Big Lebowski at Montreal's Just For Laughs Comedy Festival. It was never revealed if Patrick Stewart will have a cameo appearance, but several months ago, Ian McKellen said in February that he will be back as Magneto, although that was never confirmed.

X-Men: Apocalypse is set in the year 1983, 10 years after the events of last year's X-Men: Days of Future Past. The story centers on the villainous Apocalypse (Oscar Isaac), as he gathers his Four Horsemen on a mission to destroy the world as we know it. The Horsemen include Alexandra Shipp's Storm, Ben Hardy's Angel, Olivia Munn's Psylocke and Michael Fassbender's Magneto, who has been living a life of refuge in Poland for the past decade.

After Xavier (James McAvoy) and Mystique (Jennifer Lawrence) learn about Apocalypse's evil plan, they recruit a group of young mutants to stop him. These characters include younger versions of Cyclops (Tye Sheridan), Jean Grey (Sophie Turner), Jubilee (Lana Condor) and Nightcrawler (Kodi Smit-McPhee). Nicholas Hoult, Lucas Till (Havok), Evan Peters (Quicksilver) and Rose Byrne (Moira McTaggert) reprise their roles from X-Men: First Class and X-Men: Days of Future Past.

It isn't known how much production is left on X-Men: Apocalypse, which is set for release on May 27, 2016. We'll be sure to keep you posted as soon as more images arrive from the set, through director Bryan Singer's social media pages. Do you have any theories as to what this giant statue may represent?
