I found an easy way to do it. It worked for me... I hope it helps:

What you need to do is to "pass" the selected items to the confirmation page and include them in the form as well as including the <input type="hidden" name="action" value="admin_action" /> so that django admin knows that it should still call an admin action. The post is just to know whether to process the query set or render the confirmation page.

# Write your admin action.
# IMPORTANT: Note the context passed to TemplateResponse

from django.contrib.admin import helpers
from django.template.response import TemplateResponse

class MyModelAdmin(admin.ModelAdmin):
    def admin_action(self, request, queryset):
        if request.POST.get('post'):
            # process the queryset here
        else:
            context = {
                'title': _("Are you sure?"),
                'queryset': queryset,
                'action_checkbox_name': helpers.ACTION_CHECKBOX_NAME,
            }
            return TemplateResponse(request, 'path/to/template.html',
                context, current_app=self.admin_site.name)

# The template
{% extends "admin/base_site.html" %}
{% load i18n l10n %}

{% block content %}
<form action="" method="post">{% csrf_token %}
    <p>The following videos will be accepted:</p>

    <ul>{{ queryset|unordered_list }}</ul>

    <div>
    {% for obj in queryset %}
    <input type="hidden" name="{{ action_checkbox_name }}" value="{{ obj.pk|unlocalize }}" />
    {% endfor %}
    <input type="hidden" name="action" value="admin_action" />
    <input type="hidden" name="post" value="yes" />
    <input type="submit" value="{% trans "Yes, I'm sure" %}" />
    </div>
</form>
{% endblock %}
