@tboyce021, I found the issue and propose a tweak to https://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/sensor/radarr.py#L217

I'll submit a PR, but wanted to post it up here first as it addresses the issue.

def get_release_date(data):
    """Get release date."""
    if 'physicalRelease' in data:
        date = data['physicalRelease']
    else:
        date = data['inCinemas']
    return date

[tboyce021]

Could inCinemas be missing too? If so, maybe using get() could help (assuming data is actually a dictonary):

def get_release_date(data):
    """Get release date."""
    date = data.get('physicalRelease')
    if not date:
        date = data.get('inCinemas')
    return date

Or an even shorter version if you're sure physicalRelease can't be present and set to None:

def get_release_date(data):
    """Get release date."""
    return data.get('physicalRelease', data.get('inCinemas'))

Then just be sure that having a None value for the attribute doesn't cause any issues if inCinemas is also missing.
