With Free trial are tv series and movies free

That depends :)

The free trial includes access to all AppleTV+ original content - that is, content developed by Apple for their TV platform.

It does not give you free access to other premium channels such as HBO, Showtime, etc., nor other streaming services such as Netflix, Amazon Prime, etc.

You can install the apps for these services and access their content, but they may require their own subscriptions.

• The Apple TV+ subscription features Apple Original content.
• Other Apple TV app Channel subscriptions have each their own free trial.
• iTunes Store movies and TV shows are for buy or rent per title, without subscription option nor free trial.
