can imovie do documentary style movie?

Last night i saw a home video done by a film student for a family event. It was amazing. While i know imovie can do voice overs, this was very different. It was a video where people were being interviewed while the audio track continued the video cut into different pictures and then back to the interviewee such as if the interviewee was talking about the person as a baby they then showed shots of him as a baby, but the talk track was in the background like a music/audio track. I have seen this done in professional documentaries, but never at a family function. However, she is a film student so she has access to and knowledge of professional software.

But is it possible with imovie? and if it can...how? Granted this kid is studying documentary film so the entire storyboard was incredible, but this one technical issue beyond her incredible talent is something i made a note to ask this board -- how did she do it! and if imovie can't can FCE. I have no interest in FCP so if its truly only accomplished with high end software....then i will leave it to the professionals....:)
