I have created a `FileManager` for my personal files. The launcher for this manager is launched by following script.

```
#!/usr/bin/python

from ui.MovieManager import MovieManager

MovieManager().showView()

```

Movie manager and other modules are situated in the `ui` and `core` packages, but when executing the file as script, I do get following error.

```
vsd@homeworks:~/homework/ws-python/movie-database$ sh Launcher.py 
from: can't read /var/mail/ui.MovieManager

```

I am not able to identify why this script is not picking up `MovieManager` module under the current folder? However when I execute command `python Launcher.py`, It works well.
