McConaughey is such an oddball choice for Sinister... I kind of like it. Similar to Kevin Bacon as Sebastian Shaw in First Class. Weird, but fun.
Not so much a problem for a guy in a suit of armor, but for an actor trying to maintain a ripped physique it gets pretty tough past about 45. Having said that, with technology being what it is today, I still say Hugh Jackman could continue playing Logan digitally for another 15 years and they just use a younger actor’s body. It’s not been done, at least not in such a high profile starring role. But the technology is now there to make it possible. Just saying. Could be an unprecedented move by Disney here.
