The one actor most likely to guarantee a great movie, according to scienceHollywood can often fall into the trap of the greats being hailed as the greatest, while the rest are all left to rot. Because of this, deciding where to put your money at the cinema can be a tough nut to crack. One thing that does stand as somewhat of a steadfast guarantee, at least most of the time, is the actors starring in any given film. Let’s not beat about the bush here: when you see certain names on a poster, you know that, for their prestige and their price tag, the movie in question is bound to be good. Among them are the likes of Florence Pugh, Carey Mulligan, and Clint Eastwood, but even they don’t take the top crown for the Hollywood actor effectively guaranteed as the beacon of a great movie.
