Jada Pinkett Smith wanted to do 'Madagascar' to make up for being rejected for 'The Lion King'.

The 41-year-old actress auditioned for the role of Simba's mother Sarabi in the 1994 family film but admits she admits being ''absolutely horrible'' so she was keen to voice the role of Gloria the hippopotamus in the computer-animated comedy franchise to make up for her previous disappointment.

She said: ''I once auditioned for Simba's mother in 'The Lion King'. And I was absolutely horrible. I had no idea what I was doing. I made myself sound like a lion, because I had no idea I could use my own voice. I felt I need to do this to make up for that faux pas in my career.''

Jada admits she had to ''become a child'' again to portray Gloria and she found herself using her imagination ''in a different way'' compared to playing an alter-ego in a live action movie because her part was recorded in a booth rather than on a set.

She added to the Daily Telegraph newspaper: ''I think you almost have to become a child to act like this. You have to use your imagination in a different way, and think what the place looks like in your scene. In this movie, for instance, we're at the circus. You have to let go all that seriousness of being an adult.''
