Should do this:
1: Not focus on Chief, but have him or another (group of) Spartan(s) act as secondary characters.
2: Choose a time in the conflict that hasn't been part of the games yet, or isn't directly interwoven with the books (for instance, a movie about GoO would be incredibly hard to follow for those new to Halo, whereas a sequel to Contact Harvest (basically between CH/Halo Wars would be better). This makes it easier accessible to newcomers, and means it wouldn't directly interfere with canon.
3: Take the raw "Saving Private Ryan in space" style the Halo trailers have been known for.
4: Focus on story, without going too deep into Forerunner influences. Make sure not everything is being tucked in...there's not even a need for Flood or Forerunners if you could focus on the Covenant alone. Don't go for action only as well.
Basically, take a look at some of the more "standalone" Halo games. Halo Wars, ODST and Reach all show how a movie could be a "standalone" thing within the larger universe. Relatively smaller scaled, and easier to follow = best option for a movie.
