making indoor audio sound like outdoor

I was doing some ADR for a film I'm working on, and the scene is outside, however, I recorded the ADR in a very silent room, so when I combined it with the scene it didn't sound natural because it doesn't sound like 'outdoor' sound - it seems like it has too much bass. I have experimented with some reverberation filters but have not gotten decent results. Are there any other audio filters I should play around with to make it sound more like outdoor sound? I am using Final Cut Pro HD - I would greatly appreciate any feedback. Thank you!
 
Depending upon the type of microphone used (cardioid or hyper-cardioid) there can be excessive low frequency emphasis in the mid bass region (80 - 150 Hz) that occurs with closely miked subjects. This does not usually occur in outdoor recordings, so you might want to notch down that region a small amount. Adding reverberation is not likely to be of any value as exteriors have less natural reverberance as their boundaries are much further than a small room would have. If anything, you would likely want to reduce the reverberance not increase it.

If you have the option, place your subject as far back as possible when trying to get an exterior character to your ADR. If possible, get some 'wild sound' from the location that you are trying to emulate to mix with the ADR, that will help to keep the two environments more similar in character.
 
Use SoundForge and its Acoustic Mirror. It will manipulate the audio to make it sound like any of a number of venues: outside in a pine forest or a valley, concert halls, churches, bathrooms, whatever you need. And you can add your own impulses with a little work.

reduce bass to flavour... we do lots of ADR at my film school and presence is what destroys the reality of it. Get the subject to step further away from the mic, drop the low/mid bass, and, heres another trick: try out a dynamic mic (like an SM58) as its lower sensitivity will lose most reverb from the room you in, and seems to actually sound more accurate for ext ADR sometimes
 
First if your doing ADR I hope you have a sound editing program, I don't know Final Cut Pro HD, but I'd be really surprised if it has the type of tools you need for ADR.
Second you should have recorded "room tone" even outside. If you did you can use the room tone in addition to foley and walla to mix with your indoor dialoge to produce a very relistic sound track.
Third ADR is VERY DIFFICULT and teadious process, if your planning to film out for commercial purposes I'd hire a pro.

Best of Luck!
