Give search for home theatre door in houzz and it will give you a few ideas. But finally what you have to think or take help from interior designer is about the theme of your home as this door should also get aligned with your house theme. In general having hallway as part of home theatre is not advised so if you can change it, it would be better. But if you can't then at least install auto closure.

This is my hallway ..where we walk from living room to informal hall to kitchen....for more privacy n for using informal hall as hometheater at times I need to put doors....In hallway...such that they don't spoil my look and don't hinder day to day life...is my thought good? is this possible....or am I overdoing things. ..

If you are a vastu believer, don't make the pooja on the west wall. Pooja should be on east or north wall of the house. Don't cut your store room as you definitely need one , rather shift it on the extreme upper side of the master bedroom. Don't provide an extra door in the bedroom for the safety point of view. As I said, by giving store room space on the upper side you get the symmetry instead of the protruded wall at the entrance of the master bedroom. Bed heard board is the best in South, then East, then West. So go for first two if possible. For further queries, you,re most welcome.

1.Remove Door and Trim If you're adjusting an existing door frame in your house, first, you will have to remove the door itself and all of the trim surrounding the frame. The door is simple enough; just pull the hinge pins out of place, tapping them from beneath with a screwdriver and mallet if necessary. For the trim, wedge a flat pry bar underneath the edge on one end of a section, and gently pull the casing away from the wall. Do the same thing for all of the pieces around the door frame and carefully set them aside to reuse later. 2.Square the Opening Off It is difficult to ensure that a door will be level and square if the rough opening is not (the rough opening is the bare bones structure before any work is done to begin a door install). So, before you begin, use a carpenter’s square to check the upper corners. This will save you time and effort later on. Remember, the more accurate your measurements, the more level your door will be. 3.Shim Door Frame Placing a pre-hung door in the rough opening will give you an idea of how it will ultimately fit. This type comes complete with a pre-made frame surrounding it, so all you need to do is carefully slide it into place and shim wherever you need around the frame to level it in the opening. Remember that wooden shims can simply be made of wedges or blocks of wood. Place a level against the door frame in your existing installation to see where you need adjustments. Then, like before, place wooden shims until it sits as it's supposed to. To keep the shims in place, nail them to the hinge. Make sure you trim any excess pieces with a saw so they sit flush with the wall. 4.Get a Level Sill Next, adjust the door sill with a flat bar or wedge until it too is level. Place the wedge or bar under the latching side of the door frame and have your help hold your door so you can check to make sure whether the top of the frame, or lintel, will need more adjustment. 5.Double Check It is important in every project to double check your work. Take the time to measure the gap between the door frame and the original rough opening. Use and nail in more wedges where necessary. If you have the extra set of hands to spare, have someone re-measure if you feel it could be adjusted differently. 6.Secure Door Frame in Opening Place your blocks of wood and/or shims into the open space over the lintel, and begin attaching the door frame to the original rough opening. Again, double check each corner to be square, before completely securing it into place. Note: Do not worry about the finishing touches just yet. You can add framing to the door after applying the paneling or drywall. Also, head and side casings will finish off a new installation nicely, covering all your small shim adjustments.
