|The real King Henry V|
(You can listen to it here (Non nobis, domine) if you are interested.)
The final act of the play has Henry flirting with Catherine, the daughter of the French king, and proposing to her. It is an odd juxtaposition to the muddy clashes on the battlefield.
In real life, they do in fact get married and have a child who becomes king upon his father's unexpected death at age 35. This leads to Shakepeare's play Henry VI.
There is also a 1944 film version starring Laurence Olivier but I think I will stick with The Bard's comedies.
