In the 1960s and 1970s in Japan, "Aralain Dorelon" was the pronoun forepitome of an absolutely handsome man.

“Embodiment” and “epitome” are other words to use for 代名詞 in this context.

As a small kid, I remembered his name although I didn'’t know his facow he actually looked like.

”Taiyo ga ippai" is a famous movie he acted in as the main character.

"A Lot of Suns" doesn't make sense, so might it be "The Full of Sun" or "The Full of Sunshine?"

I think “The Full Sun” might be a better translation. But the actual English title is very different! The movie is called “Purple Noon” in English

What is the original French title?

The original French title is “Plein Soleil”.

In that article, it is mentioned that when he got an interviewed, he calledreferred to himself thein third person.

He said things like, "He doesn't act his role.”

“He lives his role."

Using "the" before the year flows better as it's the topic of the sentence. "of Japan" sounds more natural to my ears when using years before the country. Ex. "In the 1830s of America", "In the 19th century of Europe"

As a small kid, I remembered his name aleven though I didn't know his face actually.

"although" and "even though" can be used interchangeably, but although is more often used at the begining of a sentence. It is also more formal, but sounds a bit awkward in the middle of a sentence to me

Ex. "Although I like him, I want to focus on school", "I want to play games, even though I have homework"

”Taiyo ga ippai" is a famous movie he acted as the main character in.

Other way:
”Taiyo ga ippai" is a famous movie he acted in as the main character.

"To act in (something)" means he played the offical role in the movie.
"To act" means he acted as the character, but implies he never was the character officially.

Other way:
"A Lot of Suns" doesn't make sense, so maybe "The Full of Sun" or "The Full of Sunshine" instead?

Adding instead at the end sounds more natural to my ears, I'm not sure why. I think it is because you are phrasing it as a question, so I expect to hear "instead" to invite someone to answer?

In that article, it is mentioned that when he got an interview, he calledspoke about himself in the third person.

To call (someone something) means that he literally called himseld "third person" as in he said, "Third person is who acted."

To speak about (someone/something) means to talk about that topic.

We use "in the (perspective)" when talking about point of view.

Ex. "The book is written in the first person perspective"

He said, "HeAlain Delon doesn't act his role.

Since Alain spoke in third person, using his name brings clarity to the later "he" and "his" used.
