Django inlineform not adding cinema field info on save

[drifter]

I have a inline form which looks like the snapshot above but when I save the "Cinema, Movie type and Price" doesn't get added to the additional fields (each starts time is another instance of the field). For example the second line with 2015-10-02 Cinema2 will only be saved on the instance of Show 11:00so it only saves on the first instance.

This is the model Show:

class Show(models.Model):

    MOVIE_TYPES = (
        ('2', '2D'),
        ('3', '3D'),
    )

    CINEMAS = (
        ('C1', 'Cinema 1'),
        ('C2', 'Cinema 2'),
        ('C3', 'Cinema 3'),
        ('C4', 'Cinema 4'),
    )

    movie = models.ForeignKey('Movie', related_name='shows')
    venue = models.ForeignKey(Venue)
    old_details = models.TextField(blank=True, editable=False,)
    starts = models.DateField(db_index=True,)
    starts_time = models.TimeField(db_index=True,)
    couple_price = models.IntegerField(blank=True, null=True)
    vip = models.IntegerField(blank=True, null=True)
    cinema = models.CharField(
        max_length=10,
        choices=CINEMAS,
        blank=True,
        null=True
    )
    comment = models.TextField(blank=True, )
    booking_url = models.URLField(blank=True, )
    created = models.DateTimeField(editable=False, db_index=True,)
    modified = models.DateTimeField(editable=False, db_index=True,)
    price = models.IntegerField(blank=True, null=True)
    new_price = models.IntegerField(blank=True, null=True)
    movie_type = models.CharField(
        max_length=1,
        choices=MOVIE_TYPES,
        blank=True,
        null=True
    )

    class Meta:
        ordering = ['starts', 'starts_time',]
        verbose_name = 'movie show'

    def __unicode__(self):
        return u'%s - %s - %s %s' % (self.movie.name, self.venue.name, self.starts, self.starts_time)

    def save(self):
        if not self.id:
            self.created = datetime.datetime.now()
        self.modified = datetime.datetime.now()
        super(Show, self).save()

    def movie_type_str(self):
        if not self.movie_type:
            return '-'
        else:
            return self.movie_type + 'D'

and the form...

class ShowInlineForm(forms.ModelForm):

    def __init__(self, *args, **kwargs):
        super(ShowInlineForm, self).__init__(*args, **kwargs)
        theatres = Category.objects.get(slug='movie-theatres')
        self.fields['venue'].queryset = Venue.objects.filter(categories=theatres, visible=True,).order_by('name')

    class Meta:
        fields = [
            'venue',
            'price',
            'movie_type',
            'starts',
            'cinema',
            'starts_time',
        ]

in the admin.py

class MovieShowInline(admin.TabularInline):

    formfield_overrides = {
        models.TimeField: {'widget': AdminTimeWidget(format='%H:%M')},
        models.TextField: {'widget': TextInput()},
    }
    model = Show
    extra = 1
    template = 'admin/movies/show/inline_edit/tabular.html'
    form = ShowInlineForm
    exclude = ('comment', 'booking_url',)

    def queryset(self, request):
        """Do not show shows older than today """

        qs = super(MovieShowInline, self).queryset(request)
        return qs.filter(starts__gte=datetime.date.today()).order_by('venue__name', 'starts', 'starts_time')

class MovieShowAdmin(CommonAdmin):
    fields = ('name',)
    readonly_fields = ('name',)
    list_display = [
        'name',
        'modified_by',
        'created_by',
        'modified',
        'created',
        'visible',
    ]
    inlines = [MovieShowInline,]
    list_filter = ['modified', 'created', 'visible', 'showing']
