If you are new to trills and have listened to a lot of great trills in recorded pieces, then my advice is to not to think of the trills in this piece as "trills". That will make you get an image of the sound in your head/hands that is unhelpful to a beginner, as it was with me.
With the "trills" in this piece, it is helpful to just think of them as 32nd notes played 2 to the 16th notes in the accompaniment (I don't have the score in front of me, it might be 16th to the 8th?). Playing them slow and even at the start gets the "trill" like feeling in you hands and ear and then when you speed up, it retains it flavor. At high tempos, not many pianist do more than two notes per 16th in any case!
The first instinct is to try to trill the right hand as fast as possible, which for me was a mess. It was uncontrolled in pitch and duration (I could never stop it in the right place). Only when I did two trill notes to the left hand did I get it under control. And then once it is down, the trills just come naturally.
Good luck!
