You can override forms for django's built-in admin by setting form attribute of ModelAdmin to your own form class. See:

1. https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.form
2. https://docs.djangoproject.com/en/dev/ref/contrib/admin/#adding-custom-validation-to-the-admin

It's also possible to override form template - have a look at https://docs.djangoproject.com/en/dev/ref/contrib/admin/#custom-template-options

If you're looking specifically for autocomplete I can recommend https://github.com/crucialfelix/django-ajax-selects
