Daniel is in his late 20s / early 30s. 6 ft 1, athletic, born and raised in Australia, he has the look of a young Brad Pitt or Ryan Gosling. He is currently based in Mumbai, working in Bollywood and also in South Indian cinema.
He's your charming, lovable goof from another land, vain & pompous but will do what's right in the name of love and adventure. Think Chris Pratt in "Guardians of the Galaxy" or Jared Padalecki from "Supernatural". He's the master of seduction and romance (or so he thinks), but hides a vulnerability of someone desperate to be understood.
Yet Daniel is also highly intelligent. In real life, he's a mathematician who creates videos that educate hundreds of thousands of students around the world. So he can easily play intellectual characters that are sought-after specialists in their field (Doctors, Scientists, Mathematicians etc), but who are awkward and uncomfortable in their social interactions. Daniel's friends like to call him "Rain Man", which is an extreme yet plausible example.
