[FFmpeg-user] scaling and overlaying a png watermark to video

Hi, so I'm trying to resize a png watermark image, and then overlay it 
to an video like so:

ffmpeg -i input.mpg -vf "movie=wm.png [watermark];[in][watermark] 
scale=120:120,overlay=10:10 [out]" output/test.mpg

However, I'm getting the error: Too many inputs specified for the scale 
filter. If I remove the scale option, it watermarks fine (as long as the 
wm.png is smaller than the video)

ffmpeg version 0.8.2.git-8af9366

How do I scale it down and overlay the watermark?
