Depends on budget really and what method of hanging them. The real cost is the frames. Full movie posters are big, and the frames for them have big acrylic (heck if the budget allows glass, but I saw in comments you said you’re 16 so Ike gonna guess no glass).

I would say if you want multiple larger posters hung with thumbtacks just search up your favorite movie titles followed by “poster 24x36” and just find something with decent reviews.

If you want a single piece but authentic I can look at where I bought my light box authentic displays and recommend a website for frames as well.

If you just want artwork for a movie I would really recommend Etsy. Supporting artists who are fans of things your like is a great way to support artists you might otherwise never have found. Heck they may introduce you to more cool stuff.

Anyways that’s my advice. Happy shopping.

Hugh Jackman, a native Australian shouldn’t be able to play a mid west American doomsday prepper Christian repressed father figure so well in Prisoners (2013), but damn was that a great performance.

Btw not sure if this answered your question as I had a hard time telling what exactly you were asking.
