Thanks for the compliments. I was going to finish off the display by having the respective movie poster placed behind the figure.
For those who may be wondering and might now already know, these are IKEA floating shelves. The dimensions are 11 3/4x10 1/4" so the 8x11" mini movie-posters would have been perfect. My recommendation is for a solid drywall anchor but for thinner drywalls - 1/4" - 1/2" thick - I'd recommend threaded toggles as they are better at displacing the weight within a thinner drywall.
