I used a Commercial 6-pack of fixtures, simiar to what BIG linked to, but gave the halogen bulbs away and fitted them with HUE GU10 base lights: https://www.homedepot.ca/product/com...ded/1000409112
Works out to $8/fixture. Each bulb (sadly, not $8 each) can be individually turned off, dimmed, or coloured to your lighting scenes as you see fit. A good guide is to space them 4 feet apart or so.
I could fit them easily (after all drywall was done) into compact backer boxes which are fire rated, double layer with Green Glue..so decent for sound issues too. I left some wire dangling in each box, so I could wire these in after the two layers of ceiling + GG were done...hook them up and push them in. If you're doing soffit lighing, you don't need this..but I have a low ceiling and no soffit.

The fixture is super compact. You removed the junction box, install the clamp, make the connections, button up and essentially pop the fixture into the 3 1/2 hole punched in the drywall.
I like that overheat protection is in place.
These bits separate to make bulb install/replace easy.
An idea of tilt range.
Philips Hue White & Colour Ambiance LED GU10:
These are about six feet apart..OK for a theater, but 4ft would be better if your room will be task based at all. I used six HUE GU10 bulbs and about 20ft of HUE LED strips (10ft behind AT screen, 10ft on rear wall)
My kids really like firing up the tunes with friends over and using the HUE Disco app to get each light and LED strip pulsing/flashing and changing color synced with the mood and cadence of the music playing. I have the lights programmed via SmartThings and Harmony remote so they change color and dim gradually for some cool effects when media is queued up. Because each basement light (they are all zigbee bulbs) is automated, you can also control things like motion activated stairwell lights where only one light comes in with motion, and dimmed 90%. This means that a bathroom run during the movie can be done without a blast of light frying everyone's retinas :-) You can also control gentle ramping up of light levels after a movie for the same reason.
