I knew that A.J. LoCascio has provided his voice acting doubling for Chris Pratt as Emmet Brickowski for The Lego Movie 4D: A New Adventure, why this is because Chris Pratt was unavailable to reprise his original voice role as Emmet Brickowski for this film at this moment. Now I wonder why you think that Chris Pratt was unavailable to reprise his original voice role as Emmet Brickowski for The Lego Movie 4D: A New Adventure at this moment? Please let me know, thanks.
