Hey Malcolm
The color of the river is Ace Hardware "Moroccan Spice". I just printed out a pic of a muddy river and went down and matched it up. The dominate color in that module is the river and it really makes the scene I think. The epoxy covering is Envirotex Light. The trees are Super Trees and they are from Scenic Express. Super easy to make and quick. Here is a tutorial from Youtube:

You want to get 2 foliage flock colors, spring green and medium green. Mix them together and you will get a nice variation in color with your trees. Email Sandy at scenic express and ask her for these flock colors that are not yet posted on their site.
The rocks are from Cripple Bush Valley and are "rubber rocks". They come unpainted and are flexible. Paint them white first then apply artists colors of your choice in washes...allowing each layer to dry before applying the next. The river rocks are just rocks I collected from a local stream in different sizes....
The backdrop is from Backdrop Junction....much better to work with than Backdrop Warehouse....great personalized service and excellent quality. I especially love that they are self adhesive.
Glad you enjoyed the movie....more to come as I can get more of the layout finished....
