Charlie Martin
When deciding on who to cast to star in our film, we considered using Charlie as the antagonist, as he looked the most intimidating. However if we were unable to cast charlie for any specific reason, we would consider Jason Sudeikis, as they share a resemblance.
Jamie Beardsley
After we cast Charlie as the antagonist, we needed a protagonist, and our first thought was Jamie, as the character that he would be portraying was supposed to be young, and scared of what was happening, but as the film progresses he becomes stronger. However if we were unable yo use Jamie for any reason, we would consider Logan Lerman, as Lerman fits the profile of the character, and he has portrayed a similar character in the film 'Fury'
Our next casting decision was regarding that of the other main protagonist, we needed someone who was innocent looking and had a 'goofy' look to them. Shawn was perfect for this role, as he looked the part, and could portray this innocent character who the audience could feel for really well. If Shawn was unavailable for any reason, we would look into casting Jim Carrey, who shares a small resemblance to Shawn, and can play an emotional character who is innocent as seen in the film 'Eternal Sunshine of the Spotless Mind'
Our next big casting decision was that of casting the girlfriend of the innocent inmate. We needed someone who was fits the profile of the pretty girl who always ends up getting killed. We ended up deciding to cast Eve, as she fits the profile well. However if we were unable to cast Eve, we would next look to Mila Kunis, as she bares a similar appearance to Eve.
Our last big casting decision was that of an inmate who was a little crazy. Callum fits the profile of this, as there is a look to him that fits this role. Callum looks innocent, but also looks like he could be a creepy killer, which is what makes him perfect for this role. However if we were unable to cast Callum, we would look into casting Michael Cera, as Cera has the same qualities to him. As well as this, Cera can play a nasty person as seen in 'This is the End'
