Alund - you're joking right? Even though I don't have my reading glasses, I can see the large bent down bolt handle. That's not a M1 Garand but an 03A1 Springfield. Also note the large cocking piece at the rear of the bolt. That screams Springfield. Proximity of the rear sight to the receiver as well as the lack of rear aperture sights (like on the M-1C/M-1D) also says Springfield. The raised safety near the end of the bolt is also Springfield (but Mauser has this and the distinction of the cocking knob makes it not a Mauser). Note the bulge (top view) on the right side of the receiver. That also screams Springfield. Go to this link for another image of the receiver (never mind the sporterizing):

This is probably a Hollywierd image and we know it's entertainment, not education. Audie Murphy's
Red Badge of Courage and Jimmy Stewart's
Shenandoah both used Trapdoor Springfields - something not fielded until post Civil War. The old
All Quiet on the Western Front had a French sniper using a scoped Mauser 98 to kill Paul. Why should this image be an exception?
I suspect the scope mount is G&H, but there were numerous aftermarket scope mounts in the '30s-'50s and without seeing the mount, we can't tell. I do agree with the scope though as only the British and the Russians (OK, that suck Weaver M73 and the Leupold Alaskan) had turrets for adjusting for windage and elevation. The Germans and Japanese scopes lacked these features.
