“Harm can come to a young lad like that !”

OF COURSE I DO !!! I've seen every major motion picture that Peter Sellers was in and I have to say a large majority of them are not that great BUT. here's my recommendations:

Dr Strangelove. I think this is his best movie not only for him performance wise but in general its a fantastic movie and wonderful if you're into more like silly political satire stuff.

A Shot in the Dark: techinically the second Pink Panther movie but I works well as a stand alone movie. I think it's the best movie in the Pink Panther series because it balances out the silliness. The first Pink Panther is boring when Clouseau isn't on screen and I find the rest of the Pink Panthers to be too silly and slap stick for my tastes.

Being There: I put this one 3rd because its much drier comedy wise and takes itself a little more seriously. It has a similar vibe to Harold and Maude in my opinion? But that's probably because those are the only two Hal Ashby movies I've seen.... It's definitely a testament to Peter's talent as an actor and some of his best work. Like I said I think it leans a little drier, but it still has tons of really funny bits of comedy throughout. I cried.

Honorable mentions:

I think the Ladykillers is a great and silly movie where Peter isn't really the focus but I think his character is really cutie and charmingly silly.

The Naked Truth is also a great movie that sort of shows off Peter's range for comedic characters and I like his acting in that movie.

And this is my somewhat unpopular opinion but I really like The Magic Christian.... its the most 1969 movie you will ever watch and its kind of like if Head (1968) and Bedazzled (1967) had an ugly baby... its kind of stupid and bad but it has ringo starr and john cleese and graham chapman and Peter Sellers of course....

YOU should also of course listen to any of the popular episodes of the Goon Show because the Goon show is arguably the most important influence on all British comedy that came after it and I think its really fantastic and still holds up today when it comes to absurd and surreal comedy.
