With the top image of my own DVD cover I used my uncle to play the villain. Try and find someone the age of the character you are trying to portray and it will make the overall effect look more realistic. If possible, good lighting is key to a clear photo, so keep that in mind.  

You can always remove the background behind a person and impose another behind it which can make it look more professional. I went outside and took a photo of the clouds and edited both the images to black and white to give it a sinister feel. Don't be afraid to mess around with photo editing software. Even if you don't have Photoshop there are many websites that can do similar effects. Adjust the exposure and shadowing to achieve the look you want. Word even gives you options to change colours and also remove backgrounds so go for it!
