But folks at Gamepressure pushed the image through a software called Focus Magic. And from there, a number of words like Cerberus, Geth, Reaper and Tali’Zorah can be made out. That last one especially is a strong reference to Bioware’s Mass Effect, being a recurring character in the trilogy. The visible paragraph may also be the Mass Effect 3 entry on Wikipedia.
Whether or not there will really be a Mass Effect movie or series, only Cavill and the people behind them will know. It may not even be a film or series, but a voice role in the next instalment, even if the image suggests otherwise. But until an official announcement happens, it’s probably better to not think too much about it.
