There is a lot excitement in the acting craft and most actors don't want to do anything to diminish that. Many actors get a rush from performing in front of people and many actors just enjoy surprising themselves. There's a problem that arises when an actor allows this excitement to take precedence over creating a solid acting performance. Acting can't be a selfish exercise for long or else the audience will stop watching.

To get to where your portrayal can reach a level where you hit on something the audience cares to watch, you need to know the material till the excitement wains. The excitement will still be there ahead of time and after the performance, but the actual acting itself won't be the bundle of adrenaline it once was. If you aren't sure you need to rehearse to boredom, consider the benefits.

Improvise Inflection

When you know the words so well you needn't think about it, you can give conscious thought to how the lines are delivered. Instead of worrying about what your next line is, you can give your attention over to how you can say that line with the intent that it bears. Rather than using brainpower to remember the word, use it to come up with new ways to get that point across with the way you say it.

Improvise Stage Business

Along with inflection being something on which you can concentrate is body language and physical actions. For instance you can add emphasis to a line by walking closer to your scene partner as you deliver it. If there is a seemingly benign line you want to give some heft to, break a pencil right after you say it. The idea is to be able to free yourself to have your body serve your performance rather than be timid as you strain to recall what to say.

Feel Body Subtleties

When your brain is busy with retrieving words you are to say next your normally sensitive nerves will be ignored. Whereas sitting in the audience you can feel when your nose itches, on stage this won't likely come to mind organically if you are hopped up on performing. Once you are calm and collected on stage, you can play with reactions to heat on your body or hair falling in your face that you would otherwise not notice. It's just a way to add a little realism to your scene.

Concentrate On Character Objective

You can't help but put too much emphasis on the act of remembering your lines if you don't know them well. This is natural but it's not what your character would be doing. The lines would come to your character naturally and he or she would be worrying about achieving their objective. Unfortunately you can't concentrate on your character's objective, because you already have one: not forgetting your lines. So you really can't fully inhabit your character until you can do it without any personal objectives at all.

These are some ways that boredom with your character can be a way to be a better actor. Some think nerves are necessary for acting but it's not so. In fact when you aren't excited but can still get yourself to do the scene you can more accurately be that character. Don't run on excitement alone. Find another reason that is compelling so excitement doesn't hold you captive.
