Some 1.85 flat films are "hard matted" -- that is, there are thick black bars between frames, and only what is intended to show on screen is printed -- while others are not. Just because there is image taking up the entire frame does not mean that enitre image is intended to be projected. The film could still be 1.85. Often you will see boom mics, etc, in the top portion of the image, and this is not intended to show on screen. The undesireable portion gets cropped by the aperture plate.
If it is determined that the film truly is 1.33 or 1.66, then yes, you need a different lens (and aperture plate!) to properly show 1.33 or 1.66 on that screen. If you show a 1.66 or 1.33 film through the same lense you use for 1.85 on that screen, something will get cut off.
Make sense?

I don't recall seeing subtitles at the top of the frame in "Lost City", which is surely a 1.85 film, the one time I ran it (who puts them up there, anyway?), but I'll take your word for it. If indeed you can't frame it to include everything that's supposed to be shown, you might just be using a lens with too short a focal legnth. You may be projecting a 1.85 picture, sure, but are blowing it up too much (and using an aperture plate with a small aperture that cuts off stuff that should be on the screen). That's all I can think of.
If you are using say a 3-inch lens, try one that's 3 1/4 or 3 1/2 inches*, take out the plate, and see if it gets those titles on the screen without anything showing on the sides (soundtrack, perfs) you don't want to see. If this works, remember you have to file out your plate to match.

Ryan, rather than futzing around with different focal lenght lenses until you find one that will show the subtitles and the supertitles (there really is text at the top of the screen?) without compromising one or the other for this particular print, it really sounds as if you need to verify that entire optical system, i.e., the lens, the aperture plate and screen masking are all in proper relationship to give you a true 1.85/1 aspect ratio on the screen. This should be done with an SMPTE Projection Alignment Test Film PA30 (sometimes referred to as RP40, which is the SMPTE specification that the test film let's you know you are conforming to or not).
If the test film IS showing that you are right on point -- you are showing exactly a 1.85 aspect ratio on the screen -- yet stuff STILL gets cut off, then it's a problem with the particular print and not your system. That said, I would bet it's the optical system being not quite on the money rather than the print. On the other hand.....
This comes to mind: subtitles are actually etched into the emulsion of a print AFTER the image has been processed. It is possible that either these sub or super titles were etched improperly. In that case, a replacement print is in order (good luck on that). If they can't give you are replaement, then, yes you can try a longer focal length lens with a 1.66 aperture plate. In an art house, having a lens/plate combo for the 1.66 format would be a common thing and going to that AR would be as easy as switching from flat to scope. In straight commercial houses, however, you pretty much will only find 1.85 and scope unless you are really lucky.
FYI, a full frame print with a soundtrack is actually 1.37/1 AR not 1.33. A full frame silent print (without a soundtrack) is 1.33/1 AR. Not to worry, it's not your fault; I am sure you've heard lots and lots of people who should know better for some strange reason still refer to pre-1950 full frame soundprints as 1.33, as if they are stuck time in the silent film era. It makes as much sense as someone refering to 2000ft reels of soundfilm as "1000 footers" because that's what silent films were shipped on some freakin 100 years ago.
