1. How can I make ModelMultipleChoiceField take those "initial" values?

This could be done in your Action_Form __init__ method using ModelMultipleChoiceField initial attribute.

As it says in the Django source code (db/models/fields/related.py) in def formfield(self, **kwargs):

        # If initial is passed in, it's a list of related objects, but the
        # MultipleChoiceField takes a list of IDs.

So you need to give it a list of IDs:

class Action_Form(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(Action_Form, self).__init__(*args, **kwargs)
        self.fields['from_company'].initial = [c.pk for c in Contact.object.filter()]
