"Cowboys and Aliens" (2011) - Western's similarity

I watched a trailer of "Cowboys and Aliens" a couple of times and I couldn't notice how many coincidences it has with animated movie "Rango" by Gore Verbinski. So I've made some screencaps, which are showing similar scenes. Are the directors a good friends or should western repeat itself?

Yes, Hollywood needs fresh ideas! But no doubt, "Cowboys and Aliens" will make a good profit.
