YES there are additional CUT SCENES and it is a sore subject among the fandom. And Warner Bros/Geffen doesn’t seem to be interested in releasing a 20th Anniversary edition with those scenes as extras *pouts*

Here’s some tags with pics you won’t find in the movie because they’re production stills or cut scenes (or unused shots from scenes that did make it into the movie, or I couldn’t tell the difference so I tagged it as both). Siiiigh. 

There are little bits in the original trailer that have these, for example:

• a few seconds’ snippet of a Theatre des Vampires stage performance
• Louis saying something like, “I can’t take this anymore” to camera
• Lestat saying something like, “I never knew what life was until it ran out in a red gush on my lips.”

I think Neil Jordan also specifically mentions some things but I haven’t watched the director commentary in a loooong time.
