Making a quick run-through of the logging module, it looks like you need
to have a Formatter object added to your Handler:

filename = '/var/log/user/movies2.log'
logFile = logging.handlers.RotatingFileHandler(filename,'a',2000,4)
formatter = logging.Formatter()
logFile.setFormatter(formatter)

...then you can call emit.
