I currently have the following figure and code

documentclass{beamer}

usepackage{tikz}



begin{document}



begin{frame}

     begin{tikzpicture}[remember picture, overlay]

            node (image) at (current page.center) {includegraphics[scale=0.5]{tj}};

            node[align=center, yshift = 1.5cm, xshift = 4cm] at (current page.center) {Tom};

            node[align=center, yshift = -1.5cm, xshift = 4cm] at (current page.center) {Jerry};

        end{tikzpicture}

end{frame}





end{document}

I want to draw two arrows from Tom and Jerry to the location of their respective faces. I know there is a way to accomplish this using Tikz node. But I am not sure how to do this without compilation errors.

Can someone help me achieve this effect?

As discussed in this great answer, it is convenient to introduce a local coordinate system on top of the image.

            begin{scope}[shift={(image.south west)},x={(image.south east)},y={(image.north west)}]

            only<1-3>{

             draw[help lines,xstep=.1,ystep=.1] (0,0) grid (1,1);

             foreach x in {0,1,...,9} { node [anchor=north] at (x/10,0) {0.x}; }

             foreach y in {0,1,...,9} { node [anchor=east] at (0,y/10) {0.y}; }            

             }

             only<2->{

             node[fill=white,font=large,inner sep=4pt] (Tom) at (0.9,0.74) {Tom};

             node[fill=white,font=large,inner sep=4pt] (Jerry) at (0.9,0.23) {Jerry};

             }

             only<3->{

             draw[ultra thick,red] (Tom) -- (0.49,0.42);

             draw[ultra thick,red] (Jerry) -- (0.66,0.23);

             }

            end{scope}



        end{tikzpicture}

end{frame}

end{document}

Of course, in the end you may want to erase the grid.

             node[fill=white,font=large,inner sep=4pt,align=center] 

                (Tom) at (0.9,0.74) {Bad\ Tom};

             node[fill=white,font=large,inner sep=4pt,align=center] (Jerry) at (0.9,0.23) 

                {Tasty\ Jerry};

             draw[ultra thick,red,-stealth] (Tom) -- (0.49,0.42);

             draw[ultra thick,red,-stealth] (Jerry) -- (0.66,0.23);

Note that you were using remember picture,overlay without actually using it. As long as you do not really make use of it I recommend dropping it. I also added the arrow heads and multiline nodes, as asked in the comments.
