5. A Very Different Take On The Flash
Season two of The Flash has been even better than the first, and with everyone from Reverse-Flash to Captain Cold, Gorilla Grodd, and Zoom having all shown up in the series, it's tough to figure out what the Scarlet Speedster's upcoming movie is going to do to differentiate itself from the wildly popular and well-reviewed CW series. Batman v Superman is going to have to do something major to make this version of Barry Allen stand out then, and while there have been rumours of an armoured costume of some sort, it's going to take a lot more than a new look to effectively achieve this! There are a couple of different ways they could go, and one pretty major twist would be to wait until his cameo in Batman v Superman to reveal that Ezra Miller is actually playing Wally West. Seeing as Batman has been operating for years, who's to say that Barry Allen couldn't have been doing the same, only to have fallen in battle years earlier, passing the mantle on to Wally as he did in the comic books? That would certainly be a surprise to those who believe they're going to be seeing another take on Barry here, but I wouldn't put it past Batman v Superman going even further than that and really leaving fans stunned. Dropping the speed force and having The Flash be one of Lex Luthor's experiments is the way I'd go to really shake things up, and would guarantee a drastically different take on the beloved hero!
